Value Collection SBRI03106000-050BX Machine Screw 5/16-18

Product Description

The VALUE COLLECTION SBRI03106000-050BX is a 5/16-18 x 6 inch slotted round head machine screw manufactured from Grade 2 steel with a zinc-plated finish. Threaded to Unified National Coarse (UNC) standards, this fastener delivers reliable clamping strength in general-purpose mechanical and structural assemblies. The round head profile provides a low-profile bearing surface, and the slotted drive accommodates standard flat-blade screwdrivers. Length is measured under the head at 6 inches. Sold in a minimum order quantity of 50 per box, making it a practical choice for production runs, maintenance stockrooms, and field service kits.

This screw is suited for light-duty to medium-duty fastening applications across a range of trade environments including mechanical rooms, equipment enclosures, HVAC component mounting, plumbing fixture assembly, and general fabrication. The zinc coating provides baseline corrosion resistance for indoor and dry-environment installations. Trade professionals, fabricators, and maintenance technicians typically stock this size for recurring assembly and repair work where standard UNC thread engagement is required.

Key Features

• 5/16-18 UNC thread for compatibility with standard tapped holes and nuts
• 6-inch length under head for deep fastening reach in thicker assemblies
• Round head slotted drive for use with common flat-blade screwdrivers
• Grade 2 steel construction for general-purpose mechanical strength
• Zinc-plated finish for baseline corrosion resistance in dry environments
• Sold in a box of 50 to support production and stocking requirements

Compatibility

Designed as a general-purpose UNC machine screw for use in standard 5/16-18 tapped holes, mating hex nuts, and coupling nuts across a wide range of mechanical and structural assemblies.

Installation Notes

Installation is performed by hand or with a flat-blade screwdriver sized to the slot width. Ensure the mating thread is clean and free of debris before driving to avoid cross-threading. Apply thread-locking compound or a flat washer as required by the specific application. For structural or load-bearing assemblies, verify that Grade 2 fasteners meet the torque and load requirements specified by the equipment manufacturer or applicable codes.
