Fasteners can be confusing. We know it can be tough to keep track of all the different standard codes, drive types, head forms, materials, and finishes - so we've created some useful reference guides and cheat sheets to help you out.
Head shapes, or head forms refer to the shape of the top of the screw. This guide shows you all the different types of head form, and their potential uses.
Drive type refers to the part of a screw that allows it to be turned and tightened. There are many types of drive available, this guide walks through your options and their benefits and downsides.
This guide shows the industry standards associated with measuring fasteners. Once you know this, you can work out the diameter, length, and pitch of any standard fastener.
The pitch of a fastener refers to the distance between threads. This guide explains the different pitches available at different sizes of metric fastener.
The pitch of a fastener refers to the distance between threads. This guide explains the different pitches available at different sizes of imperial fastener.
The pitch of a fastener refers to the distance between threads. This guide explains the different pitches available at different sizes of pipe plug.
Fasteners, in general, are available in metric and imperial diameters and lengths. Often you'll need to convert between the two, or work out alternatives - this guide will help you work out what you need.
The diameters of some screws (especially woodscrews and self-tapping screws for metal) can be described with gauge numbers, rather than metric diameters. This guide shows you how to convert between the two.
A reference guide covering what size spanner/wrench should be used with a metric hex bolt, or a hex key with a metric socket screw.
A fastener's tensile strength refers to maximum amount of tensile force that can be applied to it before it breaks. This guide shows how the various different fastener tensile strengths compare with each other.
