Value Collection R63034481 1/4-20 X 2.5 in Pan Head Slotted Screw

Product Description

The VALUE COLLECTION R63034481 is a 1/4-20 UNC machine screw designed for general-purpose fastening in industrial, mechanical, and trade applications. It features a pan head profile with a slotted drive and is manufactured from 18-8 stainless steel with a bright, uncoated finish. The 2.5-inch length is measured under the head. This fastener suits corrosion-resistant assemblies where a low-profile pan head and standard slotted drive are required. It is commonly installed by HVAC technicians, plumbers, electricians, and millwrights when securing panels, brackets, and equipment enclosures.

This screw is suited for residential and commercial applications requiring corrosion resistance and dimensional consistency. The 1/4-20 UNC thread pattern is one of the most widely used coarse-thread standards in North American trade work, making this fastener appropriate for equipment panels, junction boxes, pipe hangers, and structural brackets. The 18-8 stainless steel construction makes it a practical choice in humid or wet environments such as mechanical rooms, rooftop units, and pool equipment installations.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• Pan head profile provides a low-profile bearing surface with adequate drive recess depth
• Slotted drive accommodates standard flat-blade screwdrivers and power bits
• 18-8 stainless steel construction offers corrosion resistance in wet and humid environments
• Bright, uncoated finish maintains dimensional accuracy and does not interfere with close-tolerance fits
• Length under head measured at 2.5 inches per inch system of measurement

Compatibility

Designed as a standard 1/4-20 UNC pan head machine screw for use with any tapped hole, hex nut, or coupling nut conforming to 1/4-20 UNC thread specifications in inch-system fastener applications.

Installation Notes

Installation requires a flat-blade screwdriver or matching slotted power bit sized for a 1/4-inch pan head fastener. Verify the mating thread is clean and free of damage before driving. Do not overtorque stainless steel fasteners, as galling can occur without proper lubrication or anti-seize compound. Follow applicable equipment manufacturer guidelines and relevant codes such as the NEC or IFGC when securing electrical or gas equipment panels.
