Forgefix Countersunk Torx® Compatible Head Lightening Bolts provide a virtually stress free fixing for close to edge applications. They are self-threading and allow quick and easy installation of most masonry fixing applications. They can simply be screwed into a pre-drilled hole, without the need for a sleeve or plug. The bolts are through-fixing, eliminating the need for marking and re-positioning. They have a high load capacity due to the thread interlocking into the base material. The Torx® compatible head provides increased control, and is countersunk to sit flush to the surface of the material. The bolts have an ‘Elementech’ coating for superior anti-corrosion, which has been salt spray tested to 1,000 hours. Applications: Widely used for fixing battens, balustrades, handrails, racking and holding down machinery, plus many more installation applications. Suitable for most masonry substrates including concrete and brickwork but also for hollow block or bricks due to the nature of the thread type anchoring along the total length of the fixing.Specifications:Size: M6 x 100mm.Pack quantity: 100.
