Fastener Testing

Our Phoenix Test Laboratory offers routine tensile testing on large samples, including fasteners, nuts and bolts in a variety of sizes. Our in-house design team works with our laboratory to design and manufacture bespoke brackets to suit your sample.

Overview

Fastener testing is performed to analyse the maximum strain a bolt, nut or screw can take before failing. Wedge testing is carried out on hex or square head fasteners to understand how much stress the component can withstand, while proof load testing aims to establish the maximum load a component is able to lift without failing.

Using our 1600kN test machine, we offer fastener testing on a wide range of sample sizes, up to M42.

We have a wide range of fixtures for testing large samples, including:

Compression platens up to 750mm x 1010mm,
Fixtures for testing full-sized bolts up to M42 or 1 5/8” (UTS, Tensile, Wedge and Proof loads)
Proof loading of nuts up to M42 or 1 5/8”
3 and 4 point bend fixtures with an adjustable roller span up to 1000mm
Variety of mandrels with adaptors

If we do not already have the fixture brackets, our in-house team can design and manufacture the parts to suit your specific needs.

Full sized fasteners and bolt testing (M27, M30, M33, M36, M39 and M42, or 1 1/8” up to 1 5/8”)
Nuts (M27, M30, M33, M36, M39 and M42, or 1 1/8” up to 1 5/8”)

Our Equipment

Our test machines can cover test loads from 120N up to 1.6MN (1600kN).

Our largest test machine has a clearance of 750mm between the front columns, a bed depth of 950mm, and a vertical daylight up to 1750mm, enabling us to test very large samples and assemblies.
