Nuts and Bolts: Fasteners for Projects Big and Small

Nuts and bolts are essential fasteners across carpentry, metalwork and machinery assembly. Selecting the right size, thread type and material ensures secure joints and long-lasting results in indoor and outdoor applications.

How to select fasteners

Decide between metric and imperial threads based on existing hardware, and choose corrosion-resistant materials such as stainless or coated steel for outdoor or damp environments. Inspect grade markings and thread pitch to match load requirements and tooling compatibility.

Popular options and practical tips

• Hex and flange bolts: common for structural joins; use matching nuts and washers to distribute load.
• Machine screws and nuts: precision threads for fittings and equipment assemblies; pair with locking washers where vibration is present.
• Anchor and coach screws: ideal for timber and masonry with correct pre-drilling and anchors.

Buying in kit form or bulk packs can reduce cost and keep supplies organised, while clearance lots may offer mixed sizes at a discount. Always verify strength ratings and material specifications for safety-critical applications and use the right torque settings to avoid over-tightening.
