Value Collection SBRI03100500-100BX Machine Screw 5/16-18

Product Description

The VALUE COLLECTION SBRI03100500-100BX is a 5/16-18 x 1/2 inch round head slotted machine screw designed for general-purpose fastening in metal assemblies, fixtures, and equipment. Built from steel with a zinc-plated finish, this screw meets ASME B18.6.3 standards and carries a Grade 2 material classification. The slotted drive accepts a standard flat-blade screwdriver, making it a practical choice for maintenance work, panel assembly, and light structural applications. Sold in a box of 100, this package suits technicians and contractors who need a reliable supply of standardized fasteners on hand for routine jobs.

This screw is suited for light to medium-duty fastening applications across a range of trades, including HVAC panel assembly, electrical enclosure work, plumbing fixture mounting, and general equipment maintenance. The 5/16-18 thread size is a common unified coarse thread (UNC) specification used widely in North American equipment manufacturing. The 1/2 inch length is measured under the head, per ASME B18.6.3. The zinc plating provides basic corrosion resistance appropriate for indoor and sheltered outdoor installations.

Key Features

• 5/16-18 unified coarse thread for broad compatibility with standard tapped holes

Compatibility

Designed as a standard 5/16-18 UNC machine screw suitable for use in any application requiring an ASME B18.6.3 round head slotted fastener without a washer face.

Installation Notes

Install using a flat-blade screwdriver sized to the slot to avoid cam-out and fastener damage. Ensure the mating hole is tapped to a 5/16-18 thread before installation. Do not exceed the torque appropriate for Grade 2 steel in the mating material to avoid thread stripping. Follow applicable codes and equipment manufacturer guidelines for fastener selection in structural or pressure-bearing assemblies.
