لقم الفك ساتا المكونة من خمس قطع (1/4") و (4x25mm) موديل (GL59254)

The set uses 4 mm hex bits with a length of 25 mm, and there are five pieces included in the set.

The bits are built with S2 steel insert construction and are heat-treated for maximum strength and wear resistance. They also have a rust-resistant coating to withstand harsh environments.

Yes. They are compatible with any standard 1/4" drive ratchet, extension, or drill, offering flexible use across different tools.

This set is ideal for hex socket fasteners and fasteners that require a 4 mm hex bit, making it suitable for automotive, electrical, and general repair work.

1) Insert the 4 mm hex bit fully into a compatible 1/4" drive tool. 2) Ensure the bit is seated squarely in the fastener. 3) Apply steady, even torque and avoid sudden impacts. 4) If using a drill, set an appropriate torque/speed and avoid high-torque starts on corroded or rounded fasteners.

Wipe them clean after use, dry thoroughly, and store in their case or a designated organizer. The rust-resistant coating helps, but keeping them dry and lightly oiled can extend life.

Yes, they are suitable for use with drills or impact drivers, provided you use the correct 1/4" drive interface and avoid over-torquing or using damaged bits.

Consider the bit size you most frequently encounter (4 mm in this set), the bit length (25 mm in this set), the durability of the material (S2 steel with heat treatment), and whether you need a rust-resistant finish. If you often work with different fastener sizes, you may want to add additional sizes or sets with varied bit types.

Yes. Always wear eye protection when working with fasteners, ensure the bit is fully seated in the tool and the fastener, use steady pressure rather than quick twists, avoid using damaged or worn bits, and keep hands and clothing clear of rotating tools. Store bits securely to prevent loss or damage.
