Value Collection 350-0408-61 Socket Cap Head Screw 1/4-20

Product Description

The VALUE COLLECTION 350-0408-61 is a 1/4-20 x 1/2 inch socket cap head machine screw with a Torx T30 drive, designed for high-strength fastening applications in industrial and mechanical assemblies. Manufactured from alloy steel with a black oxide finish, this screw delivers corrosion resistance and a low-reflectivity appearance suited to precision equipment and close-tolerance assemblies. The fully threaded shank provides maximum thread engagement across the full usable length. It meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 standards, making it appropriate for applications where fastener compliance is specified in engineering documentation.

This screw is used in general mechanical assembly, tooling fixtures, machine frames, enclosures, and structural fastening where a Torx drive is preferred over hex socket for torque transfer and bit engagement. The socket cap head profile keeps the fastener head low-profile relative to the clamping surface. Sold in multiples of 100 per order, this item is suited for shop inventory, MRO replenishment, and production-line consumption.

Key Features

• 1/4-20 thread size, 1/2 inch length under head, fully threaded
• Torx T30 drive for improved torque transfer and reduced cam-out
• Alloy steel construction for high tensile strength
• Black oxide finish for mild corrosion resistance and low reflectivity
• Meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 standards
• Minimum order quantity of 100 pieces per order

Compatibility

Designed as a standard 1/4-20 UNC socket cap head machine screw suitable for use wherever ANSI B18.3 socket cap fasteners are specified in mechanical and industrial assemblies.

Installation Notes

Installation is performed with a T30 Torx driver or bit. Ensure mating threads are clean and free of debris before driving. Follow applicable engineering torque specifications for 1/4-20 alloy steel fasteners as defined in the assembly documentation. Do not exceed the rated drive engagement depth to avoid stripping the Torx socket.
