Screw Torx SCHROFF 3.0 x 20 mm, Torx head, pack of 100

Screw Torx SCHROFF 3.0 x 20 mm, Torx head, pack of 100 are precision fasteners designed for electronic and mechanical assemblies where reliable torque transfer and reduced cam‑out are required. Each screw measures 3.0 mm in diameter with a 20 mm length and features a Torx drive head that provides improved engagement with compatible drivers. Supplied in a pack of 100, these screws are intended for repeated installation and removal in applications such as small parts assembly, chassis and rack mounting, and other precision fastening tasks.

Advantages

The Torx head design reduces driver slippage and allows higher torque application without damaging the screw head or the mating component. The consistent dimensions and stable drive engagement enable repeatable results during assembly and maintenance. Packaged as a set of 100, the screws offer convenient stocking for production runs and service operations, minimizing interruptions caused by part shortages.

Suitable for

• Electronic enclosures and PCB mounting
• Rack and chassis fastening in server and telecom equipment
• Small mechanical assemblies and precision equipment
• Repair and maintenance tasks requiring repeated removal

Key specifications

• Diameter: 3.0 mm
• Length: 20 mm
• Drive type: Torx head
• Quantity: 100 pieces per pack
• Intended use: machine screws for metal or plated components in electronics and mechanical assemblies

How to use

Select a driver with a matching Torx size to ensure full engagement with the Torx head. Align the screw with the threaded hole or mating nut, and apply steady axial pressure while turning the driver to prevent cam‑out. Tighten to the torque value specified for the mating material and screw size to avoid stripping threads or over‑compressing components. For repeated assembly and disassembly, inspect heads and threads for wear and replace screws that show deformation.

Usage recommendations

Use a calibrated Torx driver and follow the equipment manufacturer’s torque specifications. For sensitive electronic assemblies, consider using a torque-limiting driver and appropriate washers or threadlocker where vibration or loosening is a concern. Store the pack in a dry, dust‑free environment to maintain part quality.
