AFASTENER known as Tap-It can be used for the attachment of linings, signs, door hinges and internal wiring and for the exterior or interior installation of accessories. The fastener is corrosion-proof and a highly favourable holding power is claimed.
Essentially comprising a nylon shell and a zinc-plated drive screw, the fastener is virtually a non-conductor of heat, and is therefore particularly suitable for attaching the linings in refrigerated bodywork. The nylon is shred proof.
Because of its expanding grip action, the Tap-It can be employed with equal facility to solid or hollow structures of any type of material, including concrete, plastics, timber, glass fibre, metal, tiles, plasterboard and so on. It is claimed to be vibration resistant.
