Products & Services

HEICO-LOCK® wedge lock washers are the perfect solution to ensuring a bolted joint will not self-loosen even under the most trying conditions. Dynamic shock loads and high vibration are the bane of keeping bolted joints tight. These bolted joint stresses are no match for our wedge locking system. The bolt security value is immediately apparent, not only initially, but over the lifespan of the application.

HEICO-TEC® Tensioning Systems provide a cutting edge solution for accurately securing large diameter bolted joints. They are an exceptional overall value, are safe, repeatable, fast and especially ideal for tight spaces. HEICO-TEC’s® internal design elements vastly improves the elasticity of a bolted joint resulting in an application’s longer life span. HEICO supports both standard, off the shelf availability and custom tensioners to meet specific design requirements.
