Description
Overview
Washers distribute load, protect mating surfaces, improve seating and support locking or sealing depending on the washer type. The correct washer should match the fastener diameter and the joint function.
This selected size is specified with diameter M24, thread M24.
Sold in multiples of '100 pieces. 1 Box = '100 pieces.
Material, Grade & Strength
The material and grade should be matched to the load, environment and mating components used in the assembly.
Finish & Corrosion Protection
Hot dip galvanising gives a heavier zinc coating for improved corrosion protection in outdoor or exposed conditions.
Typical Uses
Washers are used under bolt heads and nuts to spread load, protect surfaces, improve seating and provide locking or sealing support depending on the washer type.
Technical Tips
- Match the washer inside diameter to the fastener size.
- Use flat washers for load spreading and surface protection.
- Use spring, toothed or lock washers only where their locking function is appropriate.
- Use bonded washers where sealing against water ingress is required.
Selection Advice
Select the product by matching the thread, size, material, finish and function to the assembly. Avoid choosing only by appearance or a partial part number.
