1、Thermal treatment process improve the clamping precision and stability.
2、Finish surface with long durability.
Carefully Selected Steel with High Tensile Strength
Made from high-quality low-carbon alloy steel; threaded after quenching;
precision machining process
The handle features high hardness, excellent wear resistance, and a long service life.
Precision Grinding and Polishing
The surface undergoes precision grinding and polishing to enhance smoothness.
The body is forged as a single piece, ensuring tight metal bonding for stability,
wear resistance, and rust prevention.
Body Quenched for High Hardness
A process of carburizing followed by quenching is employed, resulting in high surface hardness,
superior wear resistance, and an extended service life.
