A screw is the very broad term used to describe a type of fastener that uses a male thread to lock both itself and the product that it is attaching into another material.
A male thread is the name given to the twisted, spiral ridge that runs along all or part of the outside of the stem of the screw.
Screws are usually made from metal and are available in a huge variety of forms to suit all sorts of applications and materials.
Choose from the following categories, each of which contains a detailed explanation of how and where to use the products in question:
• Woodscrews – the common options are twin thread, chipboard, and our premium Velocity screws
• Self-tapping screws – used to secure metal and plastics without drilling a pilot hole first
• Decking screws – used to fasten timber decking to joists.
• Self-Drilling screws – a type of self-tapping screw with a drill point on the tip. Enables screws to fasten to hard materials like steel without the need for a pre-drilled hole.
• Coach screws - often confused with coach bolts, they are generally used to fasten heavy timber items like gates and fences.
• Drywall screws – used to fasten plasterboard to timber or metal stud work
• Thread forming screws – unlike self tappers, thread forming screws are tight-fitting, anti-vibration fasteners that displace the base material to form the thread, moving it into the male thread of the screw rather than cutting it away like a self tapper does.
• Carcass screws - coarse, single thread woodscrews with sharp points that are used in the furniture industry.
• Screw eyes, cup washers and screw hooks - Screw eyes are a threaded screw with a formed loop on the top. Cup washers are used in conjunction with countersunk screws to leave a decorative, neat finish. Screw hooks are effectively a screw with a hook on one end instead of a traditional screw head.
