Value Collection 0505MSL 5-40 X 5/16 Fillister Head Slotted Machine

Product Description

The VALUE COLLECTION 0505MSL is a 5-40 unified coarse thread machine screw with a fillister head and slotted drive, manufactured from steel with a zinc finish. The fillister head profile features a smaller diameter and taller head height compared to a standard pan head, making it well suited for counterbored holes and recessed fastening applications where a low-profile outer diameter is required. The 5/16-inch length is measured under the head per ASME B18.6.3 standards. Material grade meets SAE J82. These screws are used throughout light fabrication, electronic assemblies, instrument panels, and general mechanical assembly work.

This screw is appropriate for residential and commercial light-duty fastening applications including HVAC cabinet assembly, electrical enclosures, control panel mounting, and instrument housings where a small-diameter, fine-pitch thread pattern is needed. The 5-40 thread size is commonly found in thin-gauge metal assemblies and electronic hardware. The zinc finish provides basic corrosion resistance suitable for indoor and protected environments. Sold individually as a single piece with a minimum order quantity of 100 units.

Key Features

• Fillister head profile with reduced outer diameter for counterbored and recessed hole applications
• Slotted drive compatible with standard flat-blade screwdrivers
• 5-40 thread size, 5/16-inch length under head per ASME B18.6.3 and SAE J82
• Steel construction with zinc finish for basic indoor corrosion resistance
• No washer face — plain underhead bearing surface
• Inch measurement system; meets ASME B18.6.3 fastener standard

Compatibility

Designed as a standard inch-series machine screw for use in any application requiring a 5-40 thread, fillister head, and slotted drive per ASME B18.6.3 specifications.

Installation Notes

Installation requires a flat-blade screwdriver sized to match the slotted head. Ensure the mating thread is tapped or pre-threaded to 5-40 specifications before installation. De-energize any electrical assemblies before fastening screws into panels or enclosures. Do not overtighten into thin-gauge or soft base materials, as the small thread diameter is susceptible to stripping.
