Countersunk Torx Screw SCHROFF LIKOSHR M4x6 PENTORX Pack of 100

Pack of 100 SCHROFF LIKOSHR M4x6 PENTORX countersunk Torx screws designed for flush mounting in electronics, enclosures and mechanical assemblies. Each screw features an M4 metric thread and a 6 mm overall length, with a countersunk head profile that allows the fastener to sit level with or below the surface. The PENTORX drive provides secure torque transmission and reduced cam-out compared with standard Phillips designs, ensuring reliable fastening in repeated assembly operations.

Advantages

The countersunk head enables a neat, flush installation that prevents protruding screw heads and interference with moving parts or covers. The M4 thread size and short 6 mm length are suitable for thin panels and lightweight components where a compact fastening solution is required. The PENTORX drive improves engagement between driver and screw, reducing slippage and wear on both the tool and the fastener during installation and removal.

Suitable for

• Mounting electronic PCBs and internal brackets inside enclosures
• Securing sheet metal panels and covers where flush finishing is needed
• Assembly of mechanical parts with limited material thickness
• Applications requiring repeatable torque-controlled fastening

Key specifications

• Thread size: M4 (metric)
• Overall length: 6 mm
• Head type: countersunk (flat) head for flush fitting
• Drive type: PENTORX (Torx-style) for improved torque transfer
• Pack quantity: 100 pieces

How to use

Select a PENTORX-compatible driver or bit that matches the screw drive size to ensure full engagement. Align the countersunk head with the prepared recess in the mating material so the head sits flush when tightened. Apply controlled torque according to material and mounting recommendations to avoid overtightening; when used with thin panels or soft materials, consider using a washer or backing plate to distribute load and reduce the risk of thread pull-through.

Usage recommendations

For reliable results, pre-drill or prepare a matching countersink and pilot hole appropriate for M4 threads when fastening into metal or composite panels. Use a torque-limited driver if consistent clamping force is required, and inspect fasteners periodically in applications subject to vibration.
