Grey Pneumatic 1" Drive X 77MM Deep Socket GP4077MD

Grey Pneumatic professional-grade 1" drive deep impact socket engineered for high-torque applications in the automotive, industrial, and heavy-duty maintenance sectors. Its 77mm deep-length design allows technicians to reach fasteners in restricted areas where standard-length sockets are insufficient. Constructed from premium chrome-molybdenum alloy steel and featuring the patented GP High Torque Drive, this socket ensures maximum power delivery while protecting both the tool and the fastener from rounding and premature wear.
Key Features
Deep Socket Design: Provides essential reach for accessing deep-seated fasteners in tight or recessed areas.
GP High Torque Drive: Innovative design transfers pressure from the thinnest part of the socket wall toward the thicker section for increased tool strength.
6-Point Configuration: Delivers a secure, high-contact grip on hexagonal fasteners to minimize the risk of rounding corners during high-torque use.
Industrial-Grade Material: Manufactured from high-quality chrome-molybdenum steel with precise heat treatment for the optimal balance of strength and durability.
Corrosion Resistance: Finished with a black oxide coating to protect against rust and environmental wear in harsh shop conditions.
Permanent Markings: Includes high-visibility laser-etched and roll-stamped size markings for quick and reliable identification on the job.
