DrillFast® Stainless fasteners
DrillFast® Stainless A4/316 is a high performance range of stainless steel fasteners for roofing, cladding and façade applications.
They are suitable for use on projects using aluminium sheeting or components, and in extreme environmental conditions such as marine locations where corrosion resistance is of paramount importance. Warranties are available.
Advaned manufacturing techniques ensure that DrillFast® Stainless A4/316 delivers superior drilling and tapping performance and achieves consistently high pull-out and shear values.
Designed to be different
Sophisticated manufacturing processes weld a carbon steel drillpoint to the stainless steel body. The hardened drillpoint pierces and taps into the metal substrate, pre-forming the material for the stainless thread, ensuring the fastener is totally secure while maintaining its inherent corrosion-resistance properties
Drillpoint size and thread ratio
Engineered to ensure maximum thread grip and deliver the highest level of pull-out performance without damaging the build-up.
To prevent over-driving and thread stripping in thin materials, while creating a superior seal.
To improve installation, our fasteners feature precision engineered hex heads allowing for easier driving.
Features the same pitch as the main thread for easy driving but a larger diameter to ensure the washer is clamped tightly to the top sheet of the panel, creating a weatherproof seal.
Their manufacturing methods ensure they are hardened to offer the highest pull values, while bespoke packaging ensures they don’t get ‘tangled’ in storage or transit.
DrillFast® Stainless A4/316 fasteners for sheeting, cladding and facade applications are manufactured from high-grade A4/316 (1.4401) stainless steel.A4/316 grade stainless steel is a super-austenitic alloy containing high levels of molybdenum, nitrogen and nickel, ensuring it is highly resistant to corrosion, tarnishing and stress.
