Description

The Apex-HD Industrial Tightening Screw is a specialized threaded fastener engineered for high-torque applications. Unlike standard screws, these are manufactured from Grade 10.9 or 12.9 Alloy Steel, providing the tensile strength required to prevent loosening under the constant vibration of a Zion Air Compressor. They often feature a fine-pitch thread for precise tensioning and a socket head (Allen) to allow for high-torque delivery in tight spaces. These screws are essential for securing Guide Inserts, fastening end-caps on Air Pistons, and maintaining the seal on Apex-HP Grease Pump manifolds.
