Apex 84388n 3/8 in Drive 1 in Impact Sae Socket

Product Description

The APEX 84388n is a 3/8 inch drive, 6-point standard impact SAE socket sized at 1 inch. It is built from Chrome Molybdenum Alloy Steel (Cr-Mo), which provides the tensile strength required to handle high-torque impact tool applications. The off-corner loading design contacts fastener flats rather than corners, reducing the risk of rounding damaged or corroded fasteners during removal. A manganese phosphate coating adds corrosion resistance for use in field and shop environments. This socket is intended for use by professional mechanics, HVAC technicians, plumbers, electricians, and other tradespeople who rely on impact-rated tooling for daily fastener work.

This socket is suited for both residential and commercial service work where a 3/8 inch drive impact socket is required. It is compatible with 3/8 inch drive impact wrenches and ratchets. The 1 inch SAE sizing makes it applicable to a range of fastener types commonly found in mechanical, HVAC, plumbing, and electrical panel installations. High visibility laser-etched size markings and a secondary hard stamping allow for fast identification in a tool bag or socket organizer.

Key Features

• Chrome Molybdenum Alloy Steel (Cr-Mo) construction for high-torque impact durability
• 6-point design provides full contact on fastener flats
• Off-corner loading reduces fastener rounding during removal
• Manganese phosphate coating resists corrosion in wet or outdoor environments
• High visibility laser-etched markings for quick size identification
• Secondary hard stamping provides a permanent backup size marking

Compatibility

Designed as a standard OEM-style impact socket for use with 3/8 inch drive impact wrenches, air ratchets, and hand ratchets requiring a 1 inch SAE standard-length socket.

Installation Notes

This socket is installed and used by professional tradespeople using 3/8 inch drive impact or hand tools. Always verify the drive size and fastener size match before applying torque. Inspect the socket for cracks or deformation before each use and remove it from service if damage is found. Do not use impact sockets with non-impact-rated torque multipliers unless the tool manufacturer explicitly permits it.
