Value Collection R63068489 Flat Head Phillips Machine Screw

Product Description

The VALUE COLLECTION R63068489 is a 1/4-20 UNC flat head Phillips machine screw sized at 1-1/4 inches overall length. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this fastener resists corrosion in wet and chemically active environments. The flat head profile sits flush with or below the mating surface when countersunk, making it a standard choice in panel, bracket, and enclosure assemblies. Installed without a washer, it threads directly into tapped holes or mating nuts. Trade professionals in HVAC, plumbing, electrical, and equipment service reach for this fastener when a clean, flush finish and corrosion resistance are both required.

This screw is suited for light- to medium-duty mechanical assemblies in residential and commercial applications. Common use cases include securing electrical enclosure panels, HVAC unit covers, junction box lids, and plumbing access plates where the fastener must resist moisture exposure over time. The 1/4-20 UNC thread is one of the most widely used coarse thread sizes in trade work, compatible with standard 1/4-20 tapped holes and hex nuts. Sold in minimum order quantities of 100 pieces per purchase, this screw is practical for stocking a service van or shop bin.

Compatibility

Designed as a standard 1/4-20 UNC flat head Phillips machine screw suitable for use in any application requiring a flush-mount fastener in a tapped hole or with a 1/4-20 nut.

Installation Notes

Install with a Phillips head screwdriver or a Phillips bit in a power driver set to appropriate torque to avoid thread stripping in softer mating materials. When countersinking, use an 82-degree countersink bit standard for inch-series flat head screws to achieve a flush seating surface. De-energize any electrical equipment and relieve system pressure before accessing panels or enclosures during fastener service. Apply an anti-seize compound if the screw will be installed into aluminum or dissimilar metal to prevent galvanic corrosion over time.
