HomeA4 Hex Composite Fasteners

A4/316 grade stainless steel composite panel fasteners

Introducing our new range of fasteners
2 ranges to self-drill light and heavy steel: up to 5mm or 15mm thick - and available as DrillFast or MatchFast.

Complementing our comprehensive range of self-drilling fasteners are our new A4/316 grade stainless steel fasteners for composite panels.

Available in both a hex head (typically for use in secret fix wall applications), and a bi-hex moulded head (for use in roof and wall applications), these fasteners have been specifically designed for increased performance.
