Countersunk Screw SCHROFF M4 x 10 mm, stainless steel, pack of 100

Countersunk Screw SCHROFF M4 x 10 mm in stainless steel is a fastening component intended for flush mounting in thin metal sheets, electronic chassis and equipment racks. Supplied as a pack of 100, this screw features a countersunk head that sits level with the mating surface to provide a low-profile connection that reduces protrusion and helps maintain clearances in confined assemblies.

Advantages

The stainless steel construction provides corrosion resistance and dimensional stability for indoor and light industrial environments. The countersunk head design enables the screw to be driven flush with the surface, improving mechanical fit and aesthetic integration while minimizing interference with sliding parts or covers. Packaged in a quantity of 100, the set is convenient for production runs, maintenance tasks and spare-part stocking.

Suitable for

• Mounting thin metal panels and electronic chassis
• Assembly and repair of server racks and enclosures
• Fastening computer components and internal brackets
• Applications requiring low-profile, flush-fit fasteners

Key specifications

• Thread size: M4
• Length: 10 mm (measured from underside of head to end of thread)
• Head type: countersunk (flat head) for flush mounting
• Material: stainless steel for improved corrosion resistance
• Pack quantity: 100 screws

How to use

Select an appropriate M4 clearance or tapped hole according to the application and prepare the mating surface so the countersink matches the screw head angle. Position the component or panel, insert the screw and drive it until the head is flush with the surface. Use an appropriate screwdriver or bit to avoid cam-out and to ensure the head is not damaged during tightening. For thin-sheet applications, verify that the screw length provides adequate thread engagement without protruding on the opposite side.

Usage recommendations

For reliable fastening, use a torque setting compatible with M4 stainless steel fasteners to avoid over-tightening. When assembling equipment subject to vibration, consider using a threadlocker or a spring washer to maintain clamp load. Store the screws in a dry environment to preserve corrosion resistance and inspect mating threads for damage before reuse.
