1/4"F X 3/8"M Impact Socket Adaptor / Converter From Britool Hallmark

This impact converter steps up from a 1/4-inch female square drive input to a 3/8-inch male drive output. Constructed from chromium molybdenum steel, the body handles the torque forces generated by pneumatic machinery and cordless impact drivers.

Laser markings display the Britool Hallmark logo and specific part number for clear identification. Originally developed in the 1980s for automotive workshop use, the Hallmark range features coverage against material and manufacturing defects during intentional application, excluding standard wear and tear.

All prices include VAT at the standard UK rate of 20%.
