Value Collection SBRI03101250-100BX Machine Screw 5/16-18

Product Description

The VALUE COLLECTION SBRI03101250-100BX is a 5/16-18 UNC machine screw with a round head and slotted drive, manufactured from Grade 2 steel with a zinc-plated finish. Sold in a box of 100, this fastener measures 1-1/4 inches in length under the head and is built to standard inch-system dimensions. The zinc coating provides basic corrosion resistance for general-purpose indoor applications. These screws are suited for assembly, fabrication, and maintenance work across HVAC, electrical, plumbing, and light industrial trade environments where a reliable, standardized threaded fastener is required.

This machine screw is used in a wide range of trade and light industrial applications where a 5/16-18 UNC thread pattern is specified. The round head profile sits above the work surface and distributes clamping load over a wider area, making it appropriate for general assembly, panel fastening, and equipment mounting. The slotted drive accommodates standard flathead screwdrivers or slotted bits. No washer is included or required under the head per the product specification.

Key Features

• 5/16-18 UNC thread for compatibility with standard inch-system nuts, inserts, and tapped holes
• Round head profile with slotted drive for straightforward installation with common hand or power tools
• Grade 2 steel construction provides adequate tensile strength for general-purpose fastening
• Zinc-plated finish offers basic corrosion protection in dry or low-humidity environments
• 1-1/4 inch length measured under the head per standard length measurement convention
• Boxed quantity of 100 supports high-volume maintenance and assembly work

Compatibility

Designed for use in standard 5/16-18 UNC tapped holes and with standard 5/16-18 hex nuts and threaded inserts following inch-system specifications.

Installation Notes

Installation does not require specialized trade licensing but should follow applicable mechanical codes and equipment manufacturer torque requirements. Always ensure the mating thread is clean and free of debris before driving. Use the correct slotted driver size to avoid cam-out and fastener head damage. Do not exceed the recommended torque for Grade 2 fasteners in the application material.
