Value Collection 350-5408-61 4-40 X 1/2 in Socket Cap Torx Screw

Product Description

The VALUE COLLECTION 350-5408-61 is a 4-40 x 1/2 inch alloy steel machine screw with a socket cap head and Torx drive. It features a black oxide finish and is fully threaded along its 1/2 inch length under the head. The T10 Torx drive provides a more positive engagement than a standard hex socket, reducing cam-out under torque. This screw meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 standards. Suitable for precision assembly applications in mechanical, electrical, and industrial environments, it is installed by maintenance technicians, mechanical assemblers, and field service professionals who require a compact cap-head fastener in tight clearance applications.

This screw is well suited for light-duty mechanical assemblies, control panel fabrication, enclosure mounting, and equipment maintenance tasks where a low-profile socket cap fastener is required. The 4-40 thread size and 1/2 inch length make it a common choice for securing light sheet metal brackets, small components, and circuit board standoffs in commercial and industrial equipment. The black oxide finish provides moderate corrosion resistance in dry indoor environments. Minimum order quantity is 100 pieces per order, sold as a package quantity of 1.

Key Features

• 4-40 unified coarse thread, fully threaded along the 1/2 inch grip length
• Socket cap head with T10 Torx drive for positive engagement and reduced cam-out
• Alloy steel construction for strength in compact fastener sizes
• Black oxide finish for moderate corrosion resistance in dry service conditions
• Meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 standards
• UNSPSC Code 31161501 for procurement classification

Compatibility

Designed as a standard 4-40 x 1/2 inch socket cap machine screw for use in any assembly application calling for this thread size, drive type, and head style per ANSI B18.3 specifications.

Installation Notes

Installation requires a T10 Torx driver or bit. Ensure mating threads are clean and free of debris before driving. Avoid over-torquing small-diameter 4-40 fasteners, as alloy steel screws at this size can be susceptible to thread stripping in softer base materials. Power down any electrical equipment before performing fastener service on control panels or enclosures.
