Value Collection R63094120 Machine Screw 5/16-18 Brass

Product Description

The VALUE COLLECTION R63094120 is a 5/16-18 x 2.5-inch round head slotted machine screw manufactured in brass with a bright, uncoated finish. It uses Unified National Coarse (UNC) thread form and is measured under the head at 2.5 inches. The round head profile and slotted drive make it a straightforward choice for general mechanical fastening where brass corrosion resistance and conductivity properties are needed. This screw ships without a washer and is sold in multiples of 5. It is a standard inch-system fastener suited for maintenance, repair, and fabrication work across electrical, plumbing, and mechanical trades.

This screw is used in applications where a non-sparking, non-magnetic, or corrosion-resistant fastener is required. Brass machine screws of this size are common in electrical panel work, plumbing fixture assembly, marine environments, and light industrial fabrication. The slotted drive is compatible with flat-blade screwdrivers, making installation straightforward in confined spaces where specialty bits may not be practical. Suitable for both new installation and replacement fastening in residential and commercial settings.

Key Features

• 5/16-18 UNC thread for reliable engagement with standard tapped holes and nuts
• 2.5-inch length under head for deeper fastening applications
• Brass construction offers corrosion resistance and non-magnetic properties
• Bright, uncoated finish for clean appearance and easy inspection
• Round head profile distributes load across the surface without a washer
• Slotted drive compatible with standard flat-blade screwdrivers

Compatibility

Designed as a standard inch-system UNC machine screw for use in any application requiring a 5/16-18 threaded fastener with a round slotted head in brass.

Installation Notes

Installation requires a flat-blade screwdriver sized to match the 5/16 head slot. Always ensure the mating tapped hole or nut is 5/16-18 UNC thread before driving. Power down or de-energize any electrical assemblies before fastener work in panel or fixture applications. Do not overtighten brass fasteners, as the material is softer than steel and susceptible to thread damage under excessive torque.
