Screw SCHROFF TORX-LENSKOSCHR M4x10, stainless steel, countersunk head, TORX drive

Screw SCHROFF TORX-LENSKOSCHR M4x10 is a stainless steel M4 × 10 mm countersunk fastener with a TORX drive designed for secure assembly in electronics and enclosure manufacturing. The screw provides a flush finish when installed in thin metal panels, rack systems, chassis and industrial housings where corrosion resistance and precise seating are required. Its stainless steel construction supports durability in common indoor environments and applications where a neat, low-profile head is needed.

Advantages

The countersunk head allows the screw to sit flush with the surface, reducing protrusion and enabling close mating of panels. The TORX drive improves torque transfer and reduces cam-out compared with slotted or Phillips heads, making installation and removal easier and more reliable. Stainless steel material offers inherent corrosion resistance for longer service life in standard indoor and industrial environments. The M4 × 10 mm size is a common standard for fastening thin metal parts and electronic components.

Suitable for

• Securing panels and covers in electronic enclosures
• Assembling rackmount equipment and server chassis
• Fastening brackets, rails and internal components in housings
• Applications requiring a flush, low-profile finish

Key specifications

• Thread size: M4
• Length: 10 mm (nominal)
• Head type: Countersunk (flat) head for flush mounting
• Drive type: TORX drive for improved torque transfer
• Material: Stainless steel for corrosion resistance

How to use

Select a TORX driver or bit that matches the screw head size to ensure proper engagement. Prepare the mating parts with a matching countersink or chamfer so the head can sit flush. Align the components and start the screw by hand to avoid cross-threading; then tighten with a TORX driver to the appropriate torque for M4 stainless steel fasteners, taking care not to over-tighten and deform the mating material. For repeated maintenance, inspect threads and heads for wear and replace screws if deformed.

Usage recommendations

Use compatible TORX bits and controlled torque settings when installing into thin sheet metal or delicate electronic components. If additional corrosion protection is required for harsh environments, consider using washers or coatings compatible with stainless steel and the application’s electrical requirements.
