Heico Unalloyed Steel Delta Protect Wedge Lock Washers, M12, 19.5mm External Diameter, 2.7mm Thickness, Grade A4 H-HLS-12

Heico H-HLS-12 unalloyed steel Delta Protect wedge lock washers are engineered to provide superior anti-vibration locking capabilities in tough fastening environments. Manufactured from durable unalloyed steel with a specialized Delta Protect finish, these washers resist corrosion and mechanical wear.

The wedge lock principle secures bolted joints by applying preload force, not relying on frictional locking, resulting in highly reliable and repeatable locking performance even under dynamic loads. The washers are re-usable and maintain full function throughout their life.

Complying with RoHS standards, these washers are environmentally sound and suitable for diverse industrial applications. The washers feature an external diameter of 19.5 mm, internal hole diameter matching M12 bolt size, and 2.7 mm thickness, classed as Grade A4 for enhanced corrosion resistance.

These washers are presented as pre-assembled pairs facilitating quick and secure assembly or disassembly, making them ideal for automotive, mechanical engineering, railway, wind energy, agriculture, and forestry sectors. Their design effectively minimizes bolt loosening due to vibration and dynamic stresses.
