Value Collection R63034450 Machine Screw 1/4-20 X 3/4 in

Product Description

The VALUE COLLECTION R63034450 is a 1/4-20 UNC machine screw with an oval head and Phillips drive, manufactured from 18-8 stainless steel with a bright, uncoated finish. Sized at 3/4 inches in overall length, this fastener suits general-purpose mechanical assembly where corrosion resistance and a low-profile, countersunk appearance are required. The 18-8 alloy provides solid resistance to oxidation and mild chemical exposure. Licensed tradespeople and skilled assemblers install these in equipment panels, enclosures, and fixtures across HVAC, electrical, plumbing, and light industrial applications.

This screw is suited for residential and commercial applications where a UNC thread pattern is specified and a flush-to-slightly-raised oval head profile is preferred over a flat or pan head. The Phillips drive allows fast installation with standard power tools. It is commonly used in sheet metal assemblies, equipment housings, access panels, and structural brackets where the installer needs a clean finished look at the fastener seat. These are sold in a minimum order quantity of 100 pieces per order.

Key Features

• 1/4-20 UNC thread size for wide compatibility with standard inch-series tapped holes
• 3/4-inch overall length with full-length thread engagement under the head
• Oval head profile provides a low countersunk appearance with a slightly domed top
• Phillips drive compatible with standard No. 2 Phillips bits and power drivers
• 18-8 stainless steel construction resists corrosion in humid and mildly corrosive environments
• Bright, uncoated finish maintains dimensional tolerances and allows inspection of material condition

Compatibility

Designed for use in any application requiring a 1/4-20 UNC threaded fastener with an oval head Phillips drive in an inch-measurement system. Suitable for use without a washer as specified.

Installation Notes

Install using a No. 2 Phillips screwdriver or compatible power bit. Ensure the mating hole is properly tapped or threaded to 1/4-20 UNC specification before driving. De-energize any electrical equipment and relieve system pressure before accessing panels or enclosures secured by these fasteners. Do not overtighten stainless steel fasteners, as the alloy is susceptible to galling when torque is applied aggressively without lubrication.
