Hex headed high tensile bolts and screws, together with hex drive socket head cap screws, are the mainstays of industrial fastening and as such are stocked in depth by Challenge Europe as part of their supply partnership philosophy.
Standard high tensile formats include non-flange hex head and flanged designs, along with standard socket cap head, socket button head and socket countersunk designs. Material grades available include 8.8, 10.9, 12.9 and stainless steel to suit the strength and environmental performance characteristics envisaged for the application.
Sizes are typically in the range M2 to M24 with some specifications going larger.
Supply partnership means that Challenge Europe take on the management of a customer supply chain from design specification to lineside supply using lean manufacturing principles or other optimising and integrative manufacturing philosophy to suit customer methodology.
As “the nuts and bolts of your business” people, we are pleased to announce our stock of industrial screws in metric sizes to ISO and DIN standards, also imperial to BSI and ANSI with other national/international standards available to order from recognised high quality international manufacturers. Our aim being always to ensure quality, reliability and competitive cost of assembly with consistency of supply backed by stock in depth.
High tensile bolts in 8.8, 10.9 and 12.9 are offered, many sizes from stock to meet urgent manufacturing demand. Ex-stock supply enables us to service production requirements with ongoing supply chain management in line with JIT, VMI, Kanban, Linefeed philosophies or similar integrative approaches.
This ex-stock approach enables urgent prototyping and production trials, as well as timely installation, maintenance and repair. Related stock items include self-tapping screws, self-drilling screws, thread forming screws, hammer drive screws, machine screw SEMs and wood screws.
In conjunction with our sales partners Hafren, we are delighted to offer safety and security through the medium of their primary fastener ranges. These high quality competitive fasteners are in constant demand for use in a vast range of security applications in projects all over the world. The need to safeguard against theft, vandalism and tampering is an increasingly essential part of many design specifications. To counter these threats Challenge Europe provide a comprehensive range of vandal and tamper resistant fixings and fasteners which have a varied range of uses, e.g. Architecture, Parks and Playgrounds, Automotive, Airports and Rail Stations, Prisons, Signage, Fencing, Regeneration Projects, Major Sporting Arenas, Public Venues, Street Furniture.
Standard security fasteners form a new section at www.challenge-europe.co.uk where engineers can find shear nuts and shear bolts, 2 hole (pig eye/snake eye) head machine screws, clutch head screws, pin hex head self-tappers (also 6 lobe pin head self-tappers) with Nogo™ and Armour Ring™ devices.

The team here at Challenge Europe are experts at exploiting the adaptability of simple, rugged threaded fasteners – and it is this adaptability which brings engineers to their use. Simple to use and to provide with vibration resistance, improved sealing, load spreading or good looks by combining with a range of washer accessories to enhance the performance of the basic fastener.
Crinkle, wavy washers, coil spring washers and serrated tooth lock washers each offer anti-vibration resistance in varying degrees whilst two-piece wedge lock washers such as Nord Lock provide a much greater resistance to vibration loosening. Belleville washers provide a combined profile of characteristics by offering continuous load anti-vibration and cushioning effects.
Where liquid control is required, then a sealing ring of some sort is usually called for, often in nylon, fibre or rubber, or perhaps a composite bonded type like a Dowty washer. More specialist items such as Dubo Ring washers extend liquid sealing into pressure retention, combined with vibration resistance.
Our expert team are often called upon to accessorise for a decorative finish, frequently with a soft or even fragile substrate and find that something as low tech as a cup washer fits the bill in attractive finish and providing a light load spreading function.
Ex-stock rivet nuts and rivet bushes from Challenge Europe are frequently ideal fixing solutions by providing female threads in thin walled sections. Sheet materials are commonly difficult to integrate with more rugged bulky components since provision of solid fixing in thin sheet is often a problem – however it is a problem easily resolved with rivet nuts which compress onto the sheet, or by rivet bushes which are pressed into it.
Rivet nuts are especially useful in situations where access is limited to one side, e.g. in box sections where the tooling enables the unit to be fitted with simple lever tools or more sophisticated high volume pneumatic equipment.
Rivet bushes on the other hand require access to both sides but are cheaper and simpler to fit, especially in the manufacturing environment where they can usually be fitted to flat sheets before they are folded into chassis or enclosures or other assemblies.
The team at Challenge Europe are used to dealing with these situations in production or retro-fit/repair and can provide in zinc plated steel, stainless steel, aluminium, brass with body sections in round, serrated, hexagonal or square to suit a wide range of material gauges, e.g. rivet bushes to match 0.8mm up to 4.00mm (22 to 8 gauge).
With the addition of molybdenum, A4 stainless (ASTM 316) is significantly more resistant to corrosion than the more popular A2 (ASTM 304) and very little more expensive. Although A4 stainless is often referred to as marine grade Challenge Europe have noticed an increasing need for this highly cost-effective grade to meet the demands of non-marine industries where equipment is subjected to more demanding service conditions. The non-magnetic nature of A4 also makes it particularly suitable for use in instrument manufacture and the medical industry. Consequently, Challenge are pleased to announce ranges of ex-stock nuts, bolts, screws and washers in A4 stainless for manufacturing and service/maintenance requirements.
The exceptionally high quality and longevity of A4 grade fasteners makes them a firm favourite in UK industry. Now coupled with a service package such as Kanban, Lineside supply or Vendor Managed Inventory (VMI), Challenge Europe are able to provide design and production engineers with the fasteners they want at prices they need – and to work with purchasing departs so as to ensure smooth assembly flows.

As specialist fastener suppliers here at Challenge Europe we are “big” on socket screws – with big stock and big service to ensure UK manufacturers across the electro-mechanical industries can save costs and ensure problem-free production schedules.
Socket head cap screws are frequently the threaded fastener of choice for manual or automated assembly. Typically in metric sizes of 10.9, 12.9 and 8.8 grade of high tensile steel, as well as stainless steel. Socket head cap screws, with their knurled outer head and internal hex drive, are ideal for manual positioning and power tightening for speed and accuracy. Their sister socket shoulder screw design offers an additional precision ground shoulder for accurate location.
Lighter duty applications and fully automated assembly are facilitated with both socket countersunk and socket button head screws, dependent on the thickness of the material and the appearance desired.
Complementing the above is a full range of socket setscrews in the traditional configurations of cup point, cone point, flat and dog point.
Delivery to Kanban, Linefeed or Vendor Managed Inventory systems is available.
Our team here at Challenge Europe are finding an increasing requirement for rework, retro-fit and repair projects – often involving changes to mechanical fastenings or the fitting of electronic components such as sensors. This generally occurs in an OEM environment where perhaps a specification has been changed in the middle of a production run or a previously unforeseen service requirement is realised.
Consequently we have developed a service which provides a massive benefit to manufacturers whereby they can call in our specialist team at short notice to take a production batch away for economical rectification and speedy return to the correct specification.
As specialist fastener providers we are experienced in supply side relationships for a truely extensive portfolio of threaded and other standard/custom fasteners and can seamlessly extend that interface to include special projects.
Our team here at Challenge Europe recognise that managing the supply chain for large numbers of small fasteners is a major administrative issue for specialist manufacturers and to that end we have developed a versatile stock and supply system to take much of the worry out of this process, all under the umbrella of their BS EN ISO 9001:2015 Quality Management certification.
Our four point system encompasses stock holding and control of standard and custom fasteners – providing a central site for location, control and rapid delivery.
Inventory control by performing inventory measurement, stock re-ordering, kit and component supply, plus single point invoicing.
Site management of optimum stock quantities.
Production system integration by aligning supply side capabilities with customers preferred production system, e.g. Kanban, Line-side supply, and Vendor Managed Inventory (VMI).
