The Makita T-05577 IMPACT XPS socket adapter is engineered for use with high-torque impact drivers, providing a robust solution for fastening applications. This adapter converts a 1/4" hex shank to a 1/2" square drive, allowing for the use of 1/2-inch drive sockets with impact tools. Constructed from high-quality steel with a precisely calibrated heat-treating process, it offers enhanced durability and a matte nickel surface for corrosion resistance. The design features chamfered edges on the square drive end for easy socket installation and a retention ball to securely hold sockets in place. Its optimized Torsion Zone geometry is designed to withstand the demanding forces of impact driving, contributing to extended adapter life. This package includes 10 adapters.
