Customize
The Grey Pneumatic 4028 series groups 1" drive sockets built for professional and enthusiast use in automotive, pneumatic and heavy-duty applications. Components are manufactured from alloy steels (including chrome-molybdenum alloy in some models) and feature finishes such as powder-coating for corrosion resistance. The family includes both deep and standard profiles and multiple sizes (examples in the variant data include a 7/8" deep impact socket and a 28mm standard socket), and is engineered for use with impact, torque and pneumatic tools with a square drive system for secure engagement. Some models are tested to industrial specifications and include features such as a high-torque drive design to reduce wear; certain items are backed by a lifetime warranty. Dimensions, weight and finish vary by model to meet different application needs.
