Value Collection 1414MST 1/4-20 X 7/8 in Truss Head Slotted Screw

Product Description

The VALUE COLLECTION 1414MST is a 1/4-20 truss head machine screw designed for general mechanical fastening in trade and industrial applications. Measuring 7/8 inches in length under the head, this screw features a slotted drive for standard flat-blade installation. It is manufactured from steel with a zinc-plated finish to provide basic corrosion resistance in indoor and light-duty environments. Conforming to ASME B18.6.3 and SAE J82 standards, the 1414MST is suited for assemblies where a low-profile, wide-bearing-surface head is needed to distribute clamping load across the fastened material.

This screw is used in residential and commercial maintenance, equipment assembly, panel mounting, and general mechanical repairs where a 1/4-20 threaded fastener is specified. The truss head profile sits low and wide, making it appropriate for thin sheet metal, plastic housings, or light structural panels. Licensed tradespeople and maintenance technicians across HVAC, electrical, plumbing, and general mechanical work will find this screw compatible with standard 1/4-20 tapped holes and threaded inserts. The zinc coating suits dry to mildly humid indoor service conditions.

Key Features

• Truss head provides a low-profile, wide-bearing surface for even load distribution
• Slotted drive accepts standard flat-blade screwdrivers
• Steel construction with zinc-plated finish for basic corrosion protection
• Meets ASME B18.6.3 and SAE J82 fastener standards
• Length measured under head: 7/8 inches
• 1/4-20 UNC thread for broad compatibility with standard tapped hardware

Compatibility

Designed as a standard 1/4-20 UNC machine screw for use in any application requiring a truss head, slotted-drive fastener conforming to ASME B18.6.3 and SAE J82 specifications.

Installation Notes

Install using a flat-blade screwdriver sized to the slot to avoid cam-out and head damage. Power down or de-energize any equipment before fastening into electrical enclosures or control panels, per applicable NEC guidelines. Do not over-torque; the truss head and zinc finish can be damaged if excessive force is applied with power tools without torque control. Inspect the mating tapped hole for clean threads before installation to ensure full engagement.
