Tool set 1/4"", 3/8"", 1/2"" set 173 pcs / YT-38931 / YATO

A professional toolkit designed to meet the needs of specialized automotive and mechanical services. The socket wrenches and their drive are made of durable CrV 50BV3 chrome-vanadium tool steel. The sockets are drop-forged and calibrated using precision gauges and control devices prior to hardening.

The sockets are equipped with the AS-Drive system, which increases maximum torque by 25% while fully protecting the nut flanges, and feature a two-tone surface finish. The set also includes bits made of hard S2 steel.

The set enables work requiring very high loads and precision, allowing for a wide range of service tasks involving loosening and tightening threaded connections of various nominal sizes. The ratchets have a three-component handle and 72 teeth (5-degree working stroke).
