Value Collection R63030886 Machine Screw 1/4-20 Oval Slotted Ss

Product Description

The VALUE COLLECTION R63030886 is a 1/4-20 x 1-1/2 inch oval head machine screw designed for fastening applications that require a low-profile, finished appearance at the screw head. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this screw offers solid corrosion resistance in both indoor and outdoor environments. The slotted drive accepts standard flat-blade screwdrivers or slotted bits. The thread form is UNC (Unified National Coarse), and the listed length of 1-1/2 inches is the overall length including the head. Sold in a minimum order quantity of 100 pieces per package, this fastener is suited for production, maintenance, and repair work in the trades.

This screw is commonly used in HVAC, plumbing, electrical, and general mechanical assembly where stainless steel corrosion resistance is needed and a countersunk oval profile is preferred for a clean finished look. Typical applications include securing panels, covers, nameplates, and trim components to metal or wood substrates. The 1/4-20 UNC thread is one of the most widely specified coarse-thread sizes in trade work, making this fastener broadly useful across service and installation tasks.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes and hex nuts
• 18-8 stainless steel construction provides corrosion resistance in wet or humid environments
• Oval head profile sits partially countersunk for a low-profile, finished appearance
• Slotted drive works with standard flat-blade screwdrivers or power bits
• Bright, uncoated finish maintains dimensional accuracy and does not add coating thickness
• Overall length of 1-1/2 inches; no washer included

Compatibility

Designed as a standard 1/4-20 UNC machine screw suitable for use in any tapped hole or with any standard 1/4-20 nut that accepts an oval head, slotted fastener of 1-1/2 inch overall length.

Installation Notes

Install with a flat-blade screwdriver or slotted power bit sized to the screw head slot; an undersized bit can cam out and damage the slot. For use in a countersunk or oval-head counterbore, ensure the receiving material is predrilled and countersunk to the correct angle to seat the oval head flush. When fastening into metal, verify the tapped hole thread class matches the screw before final torque. Follow applicable mechanical and building codes for fastener selection in structural or load-bearing assemblies.
