Torx screws M4×7 SCHROFF, pack of 100 – Torx head, size M4, length 7 mm

Pack of 100 SCHROFF Torx screws M4×7 designed for secure fastening in electronic and computer equipment. These fasteners feature an M4 metric thread and a 7 mm length with a Torx head profile that improves torque transfer and reduces the risk of cam-out during tightening. The pack provides a consistent supply of identical screws suitable for assembly, maintenance and repair tasks in racks, chassis, modules and electronic enclosures where M4×7 screws are required.

Advantages

The Torx head geometry allows higher torque application compared with slotted or Phillips heads while lowering the chance of driver slippage, which helps protect fasteners and mating surfaces. The uniform M4 thread and 7 mm shaft length ensure predictable engagement depth and mechanical stability when used with compatible tapped holes or nuts. A pack of 100 offers convenience for larger projects and reduces the need for frequent reordering for routine service work.

Suitable for

• Assembly of electronic racks and server chassis
• Mounting modules and printed circuit boards into enclosures
• Routine maintenance and repair of computer equipment
• Replacement of worn or lost M4×7 fasteners in industrial and lab equipment

Key specifications

• Head type: Torx
• Thread size: M4 (metric)
• Length: 7 mm (shaft length)
• Quantity: 100 pieces per pack
• Typical applications: electronic enclosures, racks, chassis, modules

How to use

Select a correctly sized Torx driver that matches the screw head to avoid damage to the recess. Position the screw into the threaded hole or through the component into a nut, apply steady axial pressure and turn the driver clockwise until the screw reaches the required seating torque or torque-limiting stop. For repairs and assembly in electronic equipment, follow the device manufacturer’s torque specifications and grounding precautions. Inspect mating threads for cleanliness and damage before installation to ensure reliable fastening.

Usage recommendations

Store the pack in a dry, cool environment and keep the screws in their original packaging until use to prevent loss and contamination. Use a torque driver when working on sensitive equipment to apply the correct torque and avoid over-tightening. Replace any screws that show thread or head damage to maintain assembly integrity.
