Angled Ball Point Long Arm: Advanced ball end shape enables the hex wrench to smoothly drive cap socket fasteners at angles up to 25 degrees, bypassing cramped space obstructions.
Premium High-Grade Alloy Steel: Forged from high-tensile structural alloy steel to handle massive tightening torques without fracturing or deforming under load.
Industrial 50 HrC Hardness Rating: Controlled thermal tempering guarantees a hard 50 HrC tip structure, preventing rounding or stripping of fastener socket walls.
Corrosion-Proof Black Finish: Treated with a chemical black oxide surface layer that actively resists environmental rust, shop humidity, and fluid exposure.
10-Piece Imperial SAE Kit: Delivers ten precisely labeled inch-based sizes ($1/16"$ to $3/8"$) organized securely in an impact-resistant molded blow case container.
