HEICO Fastening Systems specializes in manufacturing superior engineered fastening products for securing critical bolted joints. Our family of HEICO-LOCK® wedge locking washers and HEICO-TEC® tensioning systems ensure the safety and lifespan of vital bolted connections. HEICO-LOCK® wedge lock washers are the solution to ensuring a bolted joint will not self-loosen even under the most trying conditions. Shock loads, extreme thermal influences and high vibration are the bane of keeping bolted joints tight. HEICO-LOCK® wedge lock washers will keep your bolted connections secure. HEICO-TEC® tension nuts provide an innovative option for securing 1” or larger bolted joints. HEICO-TEC® tension nuts offer an exceptional value, are safe, fast and ideal for tight spaces. HEICO-TEC® improves the elasticity of a bolted joint, lowering impacts of dynamic stress and resulting in an application’s longer life. With only a standard torque wrench, a technician in the factory or in the field can accurately tighten the largest bolted joint.
