Value Collection MSCI03100620-100B Machine Screw 5/16-18

Product Description

The VALUE COLLECTION MSCI03100620-100B is a 5/16-18 x 5/8 inch fillister head machine screw designed for general mechanical fastening applications. The slotted drive accepts a standard flat-blade screwdriver for installation and removal. Constructed from steel with a zinc-plated finish, the screw meets Grade J82 material specifications and conforms to ASME B18.6.3 and SAE J82 fastener standards. The length measurement is taken from under the head, with a length under head of 5/8 inches. This fastener is suited for use by maintenance technicians, millwrights, and tradespeople assembling or servicing mechanical equipment.

This machine screw is appropriate for light to medium-duty fastening tasks in residential, commercial, and light industrial settings. The fillister head profile offers a taller, narrower head than a pan head, providing additional drive depth for the slotted bit and reducing the risk of cam-out. Common applications include equipment panel assembly, bracket mounting, and component fastening where a recessed or close-clearance head profile is preferred. Sold in multiples of 10 units per order.

Key Features

• 5/16-18 unified coarse thread for standard mechanical fastening
• 5/8 inch length measured from under the head
• Fillister head profile provides added drive depth over flat or pan head styles
• Slotted drive compatible with standard flat-blade screwdrivers
• Zinc-plated steel finish for corrosion resistance in dry indoor environments
• Meets ASME B18.6.3 and SAE J82 standards for dimensional and material compliance

Compatibility

Designed as a standard inch-system machine screw for use in any application requiring a 5/16-18 threaded fastener with a fillister head and slotted drive, conforming to ASME B18.6.3 dimensional standards.

Installation Notes

Installation is performed with a flat-blade screwdriver sized to fit the slotted head. Ensure the mating thread is tapped or pre-threaded to 5/16-18 UNC specifications before installation. Do not overtighten, as this may strip the slot or damage the thread. Always de-energize equipment and follow applicable lockout/tagout procedures before servicing assemblies that contain these fasteners.
