Set Screws

When you need a secure, threaded fastening solution for metal-to-metal or metal-to-structure applications, set screws are a reliable choice for the trade. Designed for use with nuts or tapped holes, they provide strong, consistent clamping force across a wide range of construction and engineering tasks.

Set screws are fully threaded fasteners, typically used in conjunction with nuts and washers to create a secure bolted joint. Unlike traditional bolts with a plain shank, set screws are threaded along their entire length, making them ideal for situations where full thread engagement is required.

Commonly used by builders, fabricators and maintenance professionals, set screws are suitable for steelwork, bracket fixing, machinery assembly, structural connections and general fastening applications. Available in a range of lengths, diameters and finishes, they allow you to match the fixing to the specific load and environment involved.

Our trade-focused range of set screws offers dependable performance and consistent quality for everyday site use. Whether you’re securing framework, installing plant equipment or assembling components, these fasteners provide strength and reliability where it counts.

For solid, versatile fastening in demanding applications, set screws are an essential part of any toolbox. Keep the right sizes on hand and be prepared for a wide range of bolted connections.
