Value Collection MSPI03101500-100B Machine Screw 5/16-18

Product Description

The VALUE COLLECTION MSPI03101500-100B is a pan head machine screw designed for general mechanical fastening applications. It features a 5/16-18 unified coarse thread, a slotted drive, and a zinc-plated steel construction conforming to ASME B18.6.3 and SAE J82 standards. The fastener measures 1-1/2 inches in length under the head, providing consistent thread engagement for metal-to-metal and metal-to-substrate assemblies. Sold in a minimum order quantity of 100 pieces, this screw is well suited for production, maintenance, and repair work across industrial and mechanical trades.

This machine screw is used in a wide range of assembly and maintenance scenarios including equipment enclosures, brackets, junction boxes, panels, and light structural components. The pan head profile provides a broad bearing surface and low-profile clearance, making it appropriate for applications where a flat or oval head would be unsuitable. The slotted drive accommodates standard flat-blade screwdrivers and slotted power bits. It is commonly installed by electricians, HVAC technicians, millwrights, and general maintenance mechanics working with light steel and sheet metal assemblies.

Key Features

• 5/16-18 unified coarse thread for reliable fastening in steel and compatible substrates
• Pan head profile offers a wide bearing surface with a low-profile top
• Slotted drive compatible with standard flat-blade screwdrivers and power bits
• Zinc-plated finish provides basic corrosion resistance for indoor and sheltered environments
• Meets ASME B18.6.3 and SAE J82 dimensional and material standards
• Sold in quantities of 100 for production and service use

Compatibility

Designed as a standard 5/16-18 pan head slotted machine screw per ASME B18.6.3, suitable for use in any application requiring a Grade J82 steel fastener of this thread size and length.

Installation Notes

Install using a flat-blade screwdriver or slotted power bit sized to the screw head. Ensure mating threads are clean and free of debris before fastening. Do not overtighten, as pan head screws in zinc-plated steel are susceptible to head damage and thread stripping if torque is excessive. For applications subject to vibration or outdoor exposure, evaluate whether a locking fastener or additional corrosion-resistant finish is required.
