Value Collection 1404MSL 1/4-20 X 1/4 in Fillister Slotted Machine

Product Description

The VALUE COLLECTION 1404MSL is a 1/4-20 machine screw with a fillister head and slotted drive, manufactured from steel with a zinc finish. It features a 1/4-inch length under head and meets the ASME B18.6.3 and SAE J82 fastener standards. The zinc coating provides basic corrosion resistance for general-purpose indoor mechanical assemblies. This screw ships in single-piece packages with a minimum order quantity of 100 units, making it appropriate for stocking maintenance bins or production line use by mechanics, HVAC technicians, electricians, and plumbers who work with panel assemblies and light structural hardware.

This machine screw is suited for light-duty fastening applications in residential and commercial mechanical systems. The fillister head profile offers a deeper slot for reliable slotted-driver engagement and a narrow, raised head that works well in countersunk or close-clearance installations. Typical use cases include securing equipment covers, junction box panels, and access doors in HVAC, electrical, and plumbing equipment where a 1/4-20 threaded fastener is specified.

Key Features

• 1/4-20 thread size for wide compatibility with standard tapped holes and hex nuts
• Fillister head profile provides deeper drive recess and narrow head footprint for close-clearance installs
• Slotted drive accepts standard flat-blade screwdrivers
• Steel construction with zinc finish for general-purpose corrosion resistance
• Meets ASME B18.6.3 and SAE J82 standards for dimensional and mechanical consistency
• Sold in multiples of 100 units, suitable for bulk stocking

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring a 1/4-20 machine screw with a fillister head and slotted drive, per ASME B18.6.3 dimensional standards.

Installation Notes

Install and remove using a flat-blade screwdriver sized to the slot width to avoid cam-out and head damage. Verify that the mating tapped hole or nut is clean and properly threaded before driving. De-energize all electrical equipment and relieve system pressure on plumbing or HVAC assemblies before accessing fastened panels or covers. Do not over-torque; the zinc finish and steel base are rated for light to moderate clamping loads consistent with the fastener grade.
