Value Collection R63034644 Machine Screw 1/4-20 X 3 in

Product Description

The VALUE COLLECTION R63034644 is a 1/4-20 UNC machine screw measuring 3 inches in overall length, featuring an oval head and Phillips drive. Manufactured from grade 18-8 stainless steel with a bright, uncoated finish, this fastener delivers solid corrosion resistance in general-purpose mechanical and structural applications. The oval head profile sits slightly above the surface with a countersunk underside, providing a finished appearance where aesthetics matter alongside secure clamping. Installers in mechanical, HVAC, plumbing, and electrical trades reach for 18-8 stainless hardware when fastening panels, brackets, and equipment enclosures where moisture or cleaning agents are present.

This screw is suited for light industrial, commercial, and residential service work wherever a 1/4-20 UNC thread pattern is called out. The 3-inch overall length accommodates thicker substrates or stacked material assemblies. The Phillips drive is compatible with standard Phillips bits and manual screwdrivers, making it practical for field installation. No washer is included or required under the head for standard installations.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and hex nuts
• Oval head with Phillips drive for a flush-contoured, finished appearance
• Grade 18-8 stainless steel construction for corrosion resistance in wet or high-humidity environments
• Bright, uncoated finish — no additional surface treatment to interfere with mating threads
• 3-inch overall length suitable for thicker panels or stacked assemblies
• Inch measurement system; length measured as overall length

Compatibility

Designed as a standard 1/4-20 UNC machine screw for use in any application requiring an oval-head Phillips fastener in that thread size and length. Suitable for use with standard 1/4-20 tapped holes, hex nuts, and coupling nuts.

Installation Notes

Installation does not require a licensed trade credential, but standard fastener practices apply — ensure the mating hole or tapped insert is clean and free of debris before driving. Use a properly sized Phillips bit to avoid cam-out and head damage. Do not overtorque stainless fasteners, as 18-8 stainless is susceptible to galling; applying an appropriate anti-seize compound to threads is recommended in high-torque or high-vibration installations. Power down or de-energize any equipment before fastening electrical enclosures or panels.
