Value Collection 1464MSL 1/4-20 X 4 in Fillister Slotted Machine Screw

Product Description

The VALUE COLLECTION 1464MSL is a 1/4-20 machine screw designed for secure fastening in metal and structural applications. It features a fillister head profile with a slotted drive, making it compatible with standard flathead and cabinet-tip screwdrivers. The screw measures 4 inches length under head on a 1/4-20 UNC thread pitch. Constructed from steel with a zinc finish, it meets ASME B18.6.3 and SAE J82 standards for dimensional and mechanical compliance. This fastener ships without a washer and is sold in multiples of 5. Machinists, millwrights, HVAC technicians, and general maintenance tradespeople use this screw in panel assemblies, equipment enclosures, and mechanical subassemblies where a taller head profile is required.

The 1464MSL suits residential and light commercial applications where a full 4-inch grip length is needed on 1/4-20 threaded holes. The fillister head provides a greater bearing surface and deeper slot depth than a standard pan head, making it preferable in applications where torque transfer and driver retention matter. This fastener is appropriate for steel-to-steel and steel-to-aluminum assemblies encountered in HVAC equipment panels, electrical enclosures, and mechanical brackets. Minimum order quantity is 5 pieces per transaction.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and hex nuts
• Fillister head profile provides deeper slot and higher side wall than pan head for improved torque transfer
• Slotted drive works with standard flathead screwdrivers and cabinet-tip bits
• Steel construction with zinc finish for corrosion resistance in general indoor applications
• Meets ASME B18.6.3 and SAE J82 dimensional and mechanical standards
• 4-inch length under head accommodates thicker stack-ups and panel assemblies

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for any application requiring a 1/4-20 UNC fillister head slotted machine screw with a 4-inch length under head per ASME B18.6.3.

Installation Notes

Install using a flathead screwdriver or slotted bit sized to the head slot to avoid cam-out and slot damage. Power down and de-energize any equipment before accessing internal panels or enclosures. Verify thread engagement depth meets at least 1.5 times the screw diameter in the receiving material for full holding strength. Torque to values specified by the equipment manufacturer or applicable assembly standard, as no torque specification is defined by this fastener alone.
