Value Collection 350-5820-61 Socket Cap Head Machine Screw

Product Description

The VALUE COLLECTION 350-5820-61 is a partially threaded socket cap head machine screw designed for high-torque fastening applications in metal assemblies. It features an 8-32 thread size and a 1-1/4 inch length under head, with a T25 Torx drive that resists cam-out under load. The screw is made from alloy steel and finished in black oxide, which provides mild corrosion resistance and a low-reflectance surface. It meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 standards. Machinists, maintenance technicians, and equipment assemblers install this fastener where a low-profile cap head and secure Torx engagement are required.

This screw is suited for mechanical assemblies, industrial equipment, tooling fixtures, and precision components that require reliable thread engagement in tapped holes. The black oxide finish makes it appropriate for applications where surface contrast or reduced reflectivity is a factor. The partial threading is standard for this length and thread class, allowing the unthreaded shank to act as a shoulder guide in close-tolerance fits. It is sold in minimum order quantities of 100 pieces, making it practical for production runs, repair kits, and shop stock.

Key Features

• 8-32 thread size with 1-1/4 inch length under head for standard cap head fastening
• T25 Torx drive resists cam-out and allows higher installation torque than hex drives
• Alloy steel construction provides strength beyond standard carbon steel fasteners
• Black oxide finish delivers mild corrosion resistance and low-reflectance appearance
• Partially threaded shank suits close-tolerance and shouldered assembly applications
• Meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 fastener standards

Compatibility

Designed as an OEM-style replacement or production fastener for any application requiring an 8-32 partially threaded socket cap head screw with a T25 Torx drive in alloy steel.

Installation Notes

Installation requires a T25 Torx driver or bit rated for the torque demands of alloy steel fasteners. Ensure the mating tapped hole meets 8-32 thread standards before driving to avoid cross-threading or stripping. De-energize or lock out any equipment before servicing fastened assemblies per applicable OSHA lockout/tagout procedures. Do not use an impact driver at full torque without a torque-limiting attachment, as alloy steel screws at this size can shear if over-driven.
