There are so many varieties of screws and bolts that sorting through them all can be something of a headache. That said, we’re always up for a challenge, so we’ve put together this handy guide to everything with a thread.
Types of screws and bolts:
- Wood screws
Sharp-tipped screws for use in wood. Outdoor varieties include stainless steel, zinc-coated, and Japanned.
For fastening outside decking. Covered in a waterproof coating to protect them from the weather.
For fixing large, heavy pieces of structural wood. Masonry use requires a pre-drilled hole and a plug. They have a hex head that is turned with a socket or wrench.
These bolts have a rounded head and a square anti-spin shoulder. Used in fastening timber, they’re turned with a socket or wrench.
Specially made to be used in plasterboard. These have a trumpet-shaped ‘bugle’ head that goes into the board without tearing up the exterior.
Straight-shanked and shaped like a bolt. Slotted head is turned with a screwdriver. Pre-drill a hole to provide a strong fastening.
Mushroom-headed bolts used for fixing roofing and guttering. Double slotted with a square nut.
These create their own thread as they are being driven. Often used for fixing metal. Stainless steel or zinc-plated self-tappers are recommended outdoors to prevent rusting.
Drill point enables them to tap their own hole. Used in sheet metal and cladding. Usually hex-headed or Pozi-headed. Also available with a bonded washer to create a water-tight seal for outdoor applications.
Hex-headed bolts with a partial thread. A popular choice in construction and machinery. Tighten with a socket or wrench. Also available as fully-threaded hex set screws.
Self-tapping screws for concrete, brick, and masonry, they don’t require a wallplug. Hex-headed; use a socket driver or wrench to turn them.
These specially-treated concrete screws are resistant to corrosion, making them ideal for long-term outdoor use.
The head contains an internal hex connection that is driven with a socket. They’re handy for when a lack of space makes screwing difficult.
Designed to stay put permanently, these non-reversible screws feature a special head that can only be turned clockwise.
These come with a chrome cap that covers the head once installed to provide an attractive finish. Used in mirrors and glass.
