Value Collection 350-5410-61 Socket Cap Screw 4-40

Product Description

The VALUE COLLECTION 350-5410-61 is a 4-40 x 5/8 inch fully threaded socket cap head machine screw designed for precision fastening applications requiring a Torx drive interface. Built from alloy steel with a black oxide finish, this fastener delivers solid corrosion resistance and mechanical strength in a compact 4-40 thread form. The T10 Torx drive reduces cam-out risk compared to hex or Phillips drives, making it a reliable choice in tight-clearance assemblies. It conforms to ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 standards. Maintenance technicians, mechanical assemblers, and trade professionals working on equipment panels, enclosures, and precision subassemblies will find this screw a direct fit where 4-40 fasteners are specified.

This screw suits a wide range of light mechanical and electromechanical assembly work, including HVAC control boards, electrical enclosure mounting, panel assembly, and general equipment maintenance. The black oxide finish makes it appropriate for indoor environments or applications where a non-reflective, low-profile fastener is preferred. The socket cap head profile allows installation in recessed or countersunk areas where a standard hex head would not clear. Sold in multiples of 100 per order.

Key Features

• 4-40 thread size, 5/8 inch length under head, fully threaded
• T10 Torx drive reduces cam-out during installation and removal
• Alloy steel construction for high tensile strength in small fastener sizes
• Black oxide finish provides mild corrosion resistance and non-reflective appearance
• Meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 fastener standards
• Socket cap head profile suited for recessed and tight-clearance assemblies

Compatibility

Designed as a standard 4-40 fully threaded socket cap head machine screw conforming to ANSI B18.3 and MS16555, suitable for any application specifying a 4-40 Torx drive socket cap fastener in alloy steel.

Installation Notes

Installation requires a T10 Torx driver or bit; use of an incorrect driver size can strip the drive recess and damage the fastener. Power down and de-energize any electrical or control system before installing or removing fasteners in live panels or enclosures. Follow applicable assembly torque specifications provided by the equipment manufacturer, as this listing does not include torque values. Ensure mating threads are clean and free of debris before driving to prevent cross-threading in the 4-40 thread form.
