Value Collection MSCI0-800500-100BX 8-32 X 1/2 in Fillister Screw

Product Description

The VALUE COLLECTION MSCI0-800500-100BX is an 8-32 x 1/2 inch fillister head machine screw designed for general-purpose fastening in mechanical assemblies, enclosures, and light structural applications. Manufactured from Grade 2 steel with a zinc-plated finish, this screw provides baseline corrosion resistance suited for indoor and sheltered environments. The fillister head profile offers a taller, narrower head compared to a pan head, giving it deeper drive engagement and a smaller footprint on the mating surface. The slotted drive accepts a standard flat-tip screwdriver. Sold in a box of 100, this fastener is a practical stock item for maintenance shops, HVAC panel work, and electrical enclosure assembly.

This machine screw is appropriate for use in residential and light commercial applications where a UNC 8-32 thread is specified. Common installation scenarios include securing cover panels, terminal boards, and component mounting brackets inside HVAC units, electrical cabinets, and control enclosures. The 1/2 inch length is measured under the head. Grade 2 steel is suitable for non-structural, low-stress fastening tasks where high tensile strength is not a requirement.

Key Features

• 8-32 UNC thread for compatibility with standard tapped holes in sheet metal and machined components
• Fillister head profile provides deeper drive recess and reduced head diameter versus pan head
• Slotted drive accepts standard flat-tip screwdrivers
• Grade 2 steel construction for general-purpose, low-stress fastening
• Zinc-plated finish for basic corrosion resistance in sheltered installations
• Box of 100 pieces for bench stock and service vehicle inventory

Compatibility

Designed as a standard UNC 8-32 x 1/2 inch fillister head machine screw suitable for any application requiring this thread size and head style in inch-measurement fastening systems.

Installation Notes

Installation is performed with a flat-tip screwdriver sized to the slot width; avoid oversized drivers that can slip and damage the head. Always de-energize electrical equipment and follow lockout/tagout procedures before replacing fasteners inside control enclosures or live panels. Do not overtighten into plastic standoffs or thin sheet metal, as Grade 2 steel at this size can strip threads in softer base materials. Thread engagement of at least 1.5 times the screw diameter is recommended for secure holding.
