Heico Unalloyed Steel Delta Protect Wedge Lock Washers, M5, Thickness 1.7mm, Grade A4, RoHS H-HLS5

Heico H-HLS5 wedge lock washers are precision-engineered components made from unalloyed steel with a Delta Protect finish, offering robust anti-vibration locking properties. These washers, compatible with M5 bolt sizes, have a thickness of 1.7mm and are manufactured to grade A4 standards, ensuring excellent mechanical strength and durability.

The wedge lock washers function by utilising preload force instead of friction, providing a secure fastening for bolted joints, especially in environments subject to vibration and dynamic loads. Their reusability and resistance to quality degradation make them economical and reliable for repetitive use. These washers are supplied as pre-assembled pairs, facilitating easy installation and removal.

Conforming to RoHS compliance, these washers are environmentally safe and designed for industries requiring reliable vibration resistant fastening solutions. Typical usage includes automotive assembly, mechanical engineering applications, railway systems, wind energy technology, as well as agriculture and forestry equipment.
