Manufactured from 316 stainless steel these female threaded collar bonding fasteners have a 'sighted' circular baseplate which means that there is a hole through the baseplate through which a stud can pass. This makes them best suited to situations where the fastener will be bonded to the reverse of the laminate and fixed to by means of a stud through the laminate.

In situations where inclusion within the laminate or for mounting on the surface of the laminate, a Blind threaded collar fastener would be recommended.

How to Buy

Available in M5, M6, M8 and M10 thread sizes. Please choose the thread size required from the drop-down list at the top of the page.

Further Information

Why Use Bonding Fasteners?

In many situations, bonding fasteners are the recommended method of fixing to composite materials such as GRP/fibreglass, carbon fibre and other composite laminates. This is because composite laminates are weakened by drilling, are unsuitable for threading or tapping and are vulnerable to point-loading. Use of a bonding fastener facilitates fixing to the laminate often without drilling (retaining fibre continuity) and distributing the load over a wider area.

bigHead® bonding fasteners can be used in one of two ways; either by embedding within a laminate structure or surface bonding using a suitable adhesive such as our VM100 Black 10min Methacrylate Adhesive. Surface bonding can be either on the upper surface of the laminate, or for maximum strength the fastener can be bonded to the reverse of the laminate with the fastener passing through the laminating creating a clamping force.

The design of the perforated 'head' allows adhesive or resin to flow through the holes and locks the fastener into position, achieving high stability and strength.

All our bonding fasteners are genuine bigHead® products. bigHead® are recognised as world-leaders in the composite fastener market with their name being synonymous with the type of high quality 'big head' fasteners and fixings they supply into the composites industry, including top-marques in automotive and marine manufacture.
