Value Collection R63030969 Machine Screw 1/4-20 2.5in Oval Slotted Ss

Product Description

The VALUE COLLECTION R63030969 is a 1/4-20 x 2.5-inch oval head machine screw designed for threaded fastening applications requiring a low-profile, countersunk appearance with a smooth, finished look above the surface. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this screw offers solid corrosion resistance in wet and outdoor environments. The slotted drive accepts standard flat-blade screwdrivers. The thread form follows the Unified National Coarse (UNC) standard at 1/4-20, making it compatible with the most common tapped hole specifications in inch-measurement fabrication and assembly work.

This fastener suits light to medium-duty mechanical assembly, HVAC panel work, equipment enclosures, plumbing fixture brackets, and general trade installation tasks where stainless steel is specified for corrosion resistance. The oval head style seats into a countersunk hole and leaves a slightly rounded crown above the surface, which is common in finish-sensitive applications such as panel covers and trim work. Overall length and length under head are both 2.5 inches. Minimum order quantity is 10 pieces per order.

Key Features

• 1/4-20 UNC thread — matches standard inch-system tapped holes
• 2.5-inch overall length with full 2.5-inch length under head
• Oval head with slotted drive for flat-blade installation
• 18-8 stainless steel construction for corrosion resistance
• Bright, uncoated finish — no additional plating or coating
• No washer — installs directly against the mating surface or countersink

Compatibility

Designed for use in standard 1/4-20 UNC tapped holes in inch-measurement assemblies. Suitable for countersunk holes sized for an oval head profile in metal, plastic, or composite panels.

Installation Notes

Installation requires a flat-blade screwdriver sized to the slotted drive; an undersized driver blade can damage the slot and reduce torque transmission. Ensure the receiving hole is tapped to 1/4-20 UNC specification before driving. When installing into stainless-steel mating hardware, apply a compatible anti-seize compound to prevent galling. Verify fastener length is appropriate for the material stack-up before final installation.
