Oversized Loose Stock Selection: Available in multiple large industrial metric parameters from 11mm, 14mm, and 17mm up to heavy machinery requirements like 32mm and 36mm.
Hardened Industrial Alloy Steel: Forged from structural-tier alloy steel to deliver massive cross-sectional strength under high torque workloads.
Controlled 50 HRC Hardness Rating: Subjected to rigorous heat-tempering protocols to achieve a 50 HRC rating, protecting tips against edge-rounding or shearing under load.
Anti-Corrosion Black Oxide Surface: Coated in a deep chemical black oxide layer that shields the alloy base from environmental moisture, shop rust, and oil grime.
Dual-Leverage Right-Angle L-Shape: Classic L-profile configuration features a short arm for high-torque tightening and a long arm for deep mechanical clearance.
