Value Collection R63060266 Machine Screw 1/4-20 X 1-1/4 in

Product Description

The VALUE COLLECTION R63060266 is a 1/4-20 x 1-1/4 inch flat head slotted machine screw manufactured from 18-8 stainless steel with a bright, uncoated finish. The flat head profile sits flush with the mating surface when fully driven, making it well-suited for applications where a low-profile fastener is required. The 1/4-20 UNC thread designation indicates a nominal 1/4 inch diameter with 20 threads per inch coarse thread form. Overall length is 1-1/4 inches, which is also the length under the head. These screws are used by mechanical contractors, millwrights, electricians, and general tradespeople wherever a corrosion-resistant fastener is needed.

This screw is commonly installed in light to medium-duty mechanical assemblies, electrical enclosures, equipment panels, and HVAC unit housings where stainless steel fasteners are specified for corrosion resistance. The slotted drive accepts a standard flat-blade screwdriver, making it compatible with basic hand tools in virtually any trade environment. The bright, uncoated surface finish is appropriate for indoor and moderate outdoor exposures where 18-8 stainless alloy provides adequate protection against rust and oxidation.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes and hex nuts
• Flat head profile allows flush or countersunk installation in mating material
• Slotted drive accepts standard flat-blade screwdrivers — no specialty bits required
• 18-8 stainless steel construction provides corrosion resistance without plating
• Bright, uncoated finish — no added coating to flake, chip, or affect thread fit
• Overall length equals length under head at 1-1/4 inches — no shoulder or reduced shank

Compatibility

Designed as a standard 1/4-20 UNC flat head machine screw suitable for use with any tapped hole, threaded insert, or hex nut conforming to 1/4-20 UNC thread standards in inch-measurement applications.

Installation Notes

Installation requires a flat-blade screwdriver sized to fit the slotted head recess; use of an ill-fitting driver can damage the slot and reduce holding torque. When installing into a countersunk hole, verify the countersink angle matches the flat head geometry before driving. Stainless-to-stainless fastener installations should use an anti-seize compound to prevent galling during assembly. Follow applicable mechanical codes and equipment manufacturer specifications for fastener torque requirements.
