Fixings & Metalwork

Carriage Bolt; cup square hex, 20mm mushroom head, BZP finish (Bright Zinc Plate). Designed for bolting through timber.

Square hex refers to the square section attached to the mushroom head, this sinks into timber and stops the bolt from spinning when the nut is tightened.

Supplied with one standard hex nut, washers sold separately.

A light duty fixing for jobs where speed of installation is important.
Hammer fixings work in a similar way to screws and plugs, the hammer fixing screw has a special thread that can be hammered into the plug and loosened / screwed out if required.

Installation:
Pre-drill a 10mm pilot hole through the item that you're fixing and into the masonry or brickwork. Lightly tap the fixing through the pilot hole with a hammer until the plug is flush. EG. if you're fixing a timber wall plate, the plug fits inside the timber as well as the wall. Once the plug is flush with the timber, hit the head of the screw harder to drive it into the plastic sleeve until tight.

Minimum fixing depth: 45mm

A self-tapping Masonry Screw for brick and concrete, a popular fixing to fit window frames. An easy to use fixing that does not require plastic plugs, it has a high resistance to fire compared to nylon fixings. This screw is a friction fixing which minimises expansion stress in the base material, this allows fixing near to the edge, and gives greater loading performance than most nylon fixings.
