Value Collection 3106MSR 5/16-18 X 3/8 in Round Head Slotted Screw

Product Description

The VALUE COLLECTION 3106MSR is a slotted round head machine screw designed for general-purpose fastening in metal assemblies, fixtures, and mechanical components. Manufactured from steel with a zinc finish for corrosion resistance, this fastener meets ASME B18.6.3 and SAE J82 standards. The 5/16-18 thread size and 3/8-inch length under head make it a compact yet strong choice for light to medium clamping applications where a low-profile round head and standard slotted drive are specified. Licensed tradespeople and shop technicians working with mechanical equipment, enclosures, and brackets will find this screw suitable for a wide range of fastening tasks.

This screw is suited for use in residential and commercial settings where inch-system fasteners are required. Common applications include securing equipment panels, junction box covers, and mechanical assemblies. The zinc finish provides a degree of protection in indoor environments and lightly controlled conditions. It is sold with a minimum order quantity of 100 pieces, making it appropriate for shops, field service kits, and maintenance departments that consume fasteners in volume.
