Flat Washers, DIN 126, Mild Steel Grade 4.8, 1/2"

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.

Sold per piece. Screwman code FWBLI12H.

Material, Grade & Strength

Mild steel is an economical carbon steel option for general purpose fastening where high tensile strength is not required.

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.
