Value Collection R63030361 Machine Screw 1/4-20 X 3/4 in

Product Description

The VALUE COLLECTION R63030361 is a 1/4-20 x 3/4 inch oval head slotted machine screw machined from 18-8 stainless steel with a bright uncoated finish. The oval head profile provides a low-profile, finished appearance where the fastener head is visible on the final assembly. The Unified National Coarse (UNC) thread form is the standard for general-purpose mechanical fastening in inch-dimensioned applications. This screw is installed by maintenance technicians, millwrights, and general tradespeople across a wide range of light mechanical and structural assembly tasks. Overall length and length under head are both 3/4 inch, making thread engagement calculation straightforward.

This fastener suits residential and commercial applications where corrosion resistance is a requirement and an aesthetically flush or semi-countersunk head is preferred. Typical use cases include equipment panels, electrical enclosures, light fixtures, and general mechanical assemblies where stainless steel is specified for its resistance to rust and oxidation. The 1/4-20 UNC thread is one of the most commonly stocked thread forms in the inch-fastener system, making replacement and sourcing straightforward. No washer is included or required by the fastener design.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet or outdoor-adjacent environments
• Oval head profile delivers a low-profile, finished look on visible fastener surfaces
• Slotted drive accepts standard flat-blade screwdrivers for installation and removal
• 1/4-20 UNC thread form for broad compatibility with standard inch-system tapped holes and nuts
• Bright uncoated finish maintains natural stainless appearance without plating
• Overall length and length under head both measure 3/4 inch for consistent thread engagement

Compatibility

Designed as a standard inch-series machine screw for use in any application requiring a 1/4-20 UNC threaded hole or nut, with an oval slotted head profile. No specific OEM model compatibility was provided in the product data.

Installation Notes

Install using a flat-blade screwdriver sized to the slotted drive to avoid cam-out and head damage. Ensure the mating tapped hole or nut is 1/4-20 UNC to match the thread form before driving. De-energize any electrical assembly and relieve pressure from any pressurized system before replacing fasteners during service. Do not over-torque stainless fasteners, as 18-8 stainless is susceptible to galling; use an anti-galling compound when torque requirements are critical.
