Performance Tool 3/8" Drive 3/16" Hex Bit Socket Set (W38877) is a professional-grade hex bit socket designed for tightening and loosening 3/16-inch internal hex fasteners in automotive repair, industrial maintenance, equipment service, household repair, mechanical assembly, and general workshop applications. It uses a 3/8-inch drive system, making it compatible with standard 3/8-inch drive ratchets, torque wrenches, extensions, and other compatible manual drive tools. This 3/16-inch hex bit socket is engineered to provide a stable interface between the drive tool and internal hex hardware. The bit is designed to seat securely inside compatible hex fastener heads, helping deliver controlled torque for both tightening and removal tasks. Its compact socket format makes it useful for fasteners located in machinery, brackets, fixtures, panels, and automotive assemblies. The W38877 is constructed from chrome vanadium alloy steel for strength, durability, and resistance to structural fatigue under mechanical load. Its recessed bit geometry helps improve fastener engagement by increasing surface contact within the hex recess, reducing the risk of slippage, cam-out, and corner rounding. The polished nickel chrome-plated finish helps resist rust, corrosion, moisture, grease, oil, and workshop chemicals, while large stamped markings support quick identification in toolboxes, trays, and low-light work areas.

Select the drive tool: Choose a compatible 3/8-inch drive ratchet, extension, or torque wrench. Attach the socket: Align the square drive hole of the socket with the drive tang of the tool. Secure the connection: Press the socket firmly onto the drive tang until the detent ball locks it in place. Clean the fastener head: Remove dirt, rust, or debris from the internal hex recess to allow full bit engagement. Insert the bit: Place the 3/16-inch hex bit into the fastener recess. Seat the bit fully: Keep the bit straight and fully engaged so the recessed edges contact the fastener properly. Apply steady force: Rotate clockwise to tighten or counter-clockwise to loosen the fastener. Avoid side loading: Keep the drive tool aligned with the fastener to reduce slipping, cam-out, or bit damage. Remove after use: Pull the bit straight out of the fastener once the task is complete. Detach the socket: Press the release button on the drive tool if available, then remove the socket from the drive tang. Clean the tool: Wipe away grease, oil, moisture, dirt, or contaminants with a clean cloth. Store properly: Keep the socket in a dry toolbox, socket rail, drawer, or organizer to help preserve the finish and stamped markings.
