Value Collection MSCI0-501000-100BX Machine Screw 5-40

Product Description

The VALUE COLLECTION MSCI0-501000-100BX is a 5-40 x 1 inch fillister head machine screw with a slotted drive. It is manufactured from steel with a zinc-plated finish for corrosion resistance. The fillister head profile offers a taller head height and smaller diameter than a pan head, making it well suited for counterbored holes where a recessed or semi-recessed installation is required. This screw meets ASME B18.6.3 and SAE J82 dimensional and material grade standards. It is used in light mechanical assemblies, electrical enclosures, and general maintenance applications by electricians, HVAC technicians, and mechanical assemblers working with inch-series fasteners.

This screw is sized for 5-40 threaded applications, meaning it is a No. 5 diameter fastener with 40 threads per inch. The 1 inch length is measured under the head. It is sold in boxes of 100 pieces, making it appropriate for service shops, contractors, and maintenance teams who need a reliable quantity of standardized inch-series fasteners on hand for recurring repair or assembly work.

Key Features

• 5-40 thread size with 1 inch length measured under the head
• Fillister head style for use in counterbored or recessed hole applications
• Slotted drive compatible with standard flat-blade screwdrivers
• Steel construction with zinc-plated finish for general corrosion protection
• Meets ASME B18.6.3 and SAE J82 standards for dimensional accuracy and material grade
• Sold in a 100-piece box for stock replenishment and production use

Compatibility

Designed as a standard inch-series machine screw for use in any application requiring a 5-40 threaded fastener with a fillister head profile.

Installation Notes

Install with a flat-blade screwdriver sized to fit the slotted drive without slipping, as an undersized driver will damage the slot. Ensure the mating threaded hole or nut is clean and free of debris before driving. Do not overtighten, as the No. 5 shank diameter has limited torque capacity. Fastener installations in electrical enclosures must comply with applicable NEC requirements for hardware used in listed assemblies.
