مقبس الفك ساتا المشقوق (1/4") قياس (4mm) موديل (SC21501)

Key features include a precision-fit tip for 4.0mm slotted screws, large stamped size markings for quick identification, heat-treated construction for durability, and a robust S2 steel insert to maximize strength and long life.

Main specs: 1/4" drive compatibility, 4.0mm slotted tip, S2 steel insert, heat-treated, corrosion-resistant finish, compact design for tight spaces, and clearly marked size for easy identification.

Best for tasks requiring a precise fit on 4.0mm slotted screws, including automotive repairs, appliance servicing, electronics assembly, furniture assembly, and other DIY projects where fastener size accuracy matters.

Steps: 1) Attach the socket to a 1/4" drive ratchet or driver. 2) Align the 4.0mm tip with the screw slot. 3) Apply steady pressure and turn with the appropriate torque. 4) Keep the tool perpendicular to avoid cam-out. 5) To loosen, reverse the motion with controlled force.

The 4.0mm refers to the slotted screw size the socket is built to fit. It’s optimized for 4.0mm slotted screws and is not intended for other screw head types (e.g., Phillips or Torx). For other sizes, you’d want the corresponding slotted socket sized for those screws.

Durability comes from heat-treated construction and the S2 steel insert. For care: keep it dry, wipe off any oils after use, store in a dry toolbox, and avoid dropping or bending to maintain edge integrity.

It’s engineered to handle typical high-torque applications when used with the appropriate 1/4" drive tool and correctly sized fasteners. Always apply steady, aligned pressure and avoid side loading or excessive torque that could cause slippage.

If you work with different screw sizes, check for other slotted bit sockets in the SATA line corresponding to those sizes, such as 3.0mm or 4.5mm variants, so you have the right fit for each screw type.

To extend life: clean after use to remove debris, keep dry to prevent corrosion, store in a protective case, and avoid exposing it to heavy shocks or impacts that could misalign or deform the tip.
