Screw fasteners Toolcraft TO-5380194 safety screws 6.3 mm x 50 mm internal Torx stainless steel A2 100 pcs

Toolcraft TO-5380194 safety screws are stainless steel A2 fasteners with a nominal diameter of 6.3 mm and a length of 50 mm, supplied in a pack of 100 pieces. These screws feature an internal Torx drive designed to provide positive torque transfer and reduce cam-out during installation. Manufactured from corrosion-resistant stainless steel A2, they are suitable for environments where durability and resistance to oxidation are important. The pack quantity supports medium-scale assembly tasks and maintenance work.

Advantages

The internal Torx drive offers improved torque transmission and a lower risk of stripping compared with conventional Phillips or slotted drives. Stainless steel A2 construction provides good corrosion resistance in indoor and mildly corrosive environments, while maintaining mechanical stability under normal operating conditions. The 6.3 mm nominal diameter and 50 mm length give a balance of grip and reach for fastening assemblies where moderate penetration is required. Supplied in a pack of 100, these screws facilitate batch work and reduce the need for frequent reordering.

Suitable for

• Assembly of machinery and equipment where secure, repeatable fastening is required
• Panel mounting and structural fastening in workshops and production lines
• Maintenance and repair tasks that require corrosion-resistant fasteners
• Applications requiring internal Torx engagement to minimize driver slippage

Key specifications

• Material: stainless steel A2 (corrosion-resistant grade)
• Drive type: internal Torx
• Nominal diameter: 6.3 mm
• Length: 50 mm
• Pack quantity: 100 pieces

How to use

Select an appropriate Torx driver that matches the screw's internal Torx profile to ensure correct engagement. Prepare mating components and align holes to the screw diameter before insertion. Apply moderate, steady torque to avoid over-tightening; for assemblies requiring a specific clamp load, use a torque wrench calibrated for the specified torque value. For disassembly, reverse the procedure using the same driver type. Handle and store unused screws in a dry environment to maintain their corrosion-resistant properties.

Usage recommendations

For best results, use drivers in good condition to prevent rounding of the Torx recess. In environments with high salinity or strong chemical exposure, consider alternative stainless grades or protective coatings. When installing into softer materials, use washers or backing plates to distribute load and prevent pull-through.
