Value Collection 350-2520-61 Socket Cap Screw 5/16-24

Product Description

The VALUE COLLECTION 350-2520-61 is a 5/16-24 socket cap head machine screw designed for precision fastening in mechanical assemblies, tooling fixtures, and industrial equipment. The screw is fully threaded at 1-1/4 inches under the head and driven with a T45 Torx bit, providing higher torque transfer and reduced bit slip compared to hex socket drives. It is manufactured from alloy steel with a black oxide finish that offers moderate corrosion resistance and reduced light glare in service environments. Installation is performed by mechanical technicians, millwrights, and maintenance professionals working on equipment requiring fine-thread fasteners.

This fastener is suited for applications requiring a fine 5/16-24 thread pitch, which provides increased thread engagement and resistance to vibration loosening compared to coarse-thread equivalents. Typical use cases include machine tool assemblies, fixture plates, jigs, hydraulic component mounting, and general industrial equipment where close-tolerance threaded connections are specified. The black oxide alloy steel construction handles moderate-stress applications in dry or lightly oiled environments.

Key Features

• 5/16-24 fine thread for high vibration resistance and precision thread engagement
• Fully threaded 1-1/4 inch length under head for maximum thread engagement
• T45 Torx drive reduces cam-out and allows higher installation torque than hex socket
• Alloy steel construction provides high tensile strength for demanding mechanical applications
• Black oxide finish minimizes surface reflection and provides light corrosion protection
• Meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for any assembly specifying a 5/16-24 fully threaded socket cap screw per ANSI B18.3 with a T45 Torx drive.

Installation Notes

Installation requires a T45 Torx bit or driver. De-energize and lockout any equipment before fastener replacement or assembly work per applicable safety procedures. Use a calibrated torque wrench when a specified clamp load is required by the equipment manufacturer. Black oxide fasteners used in wet or outdoor environments should be supplemented with a compatible thread lubricant or anti-corrosion compound to prevent premature surface degradation.
