Value Collection 92998 Pan Head Machine Screw 1/4-20 X 1/2 in

Product Description

The VALUE COLLECTION 92998 is a 1/4-20 pan head machine screw with a slotted drive, manufactured from 18-8 stainless steel with a bright uncoated finish. The screw measures 1/2 inch in length under the head on a Unified National Coarse (UNC) thread form. The pan head profile provides a wide, low-profile bearing surface suited for general fastening applications. Installers working in HVAC, plumbing, electrical, or equipment assembly use this fastener where corrosion resistance and reliable thread engagement in standard clearance holes are required.

This fastener is appropriate for light-duty mechanical assembly in both residential and commercial settings. Common applications include securing access panels, mounting brackets, junction box covers, electrical enclosures, and sheet metal components. The 18-8 stainless steel construction provides good resistance to moisture and mild corrosives, making it suitable for use in humid mechanical rooms, rooftop equipment, and outdoor enclosures. The slotted drive is compatible with standard flathead screwdrivers and is a common configuration in legacy equipment and control panel fastening.

Key Features

• 1/4-20 UNC thread form for compatibility with standard tapped holes and hex nuts
• 1/2 inch length under head for shallow to mid-depth fastening applications
• Pan head geometry provides a broad clamping surface without countersinking
• 18-8 stainless steel construction resists corrosion in wet or humid environments
• Bright uncoated finish with no added plating that could affect thread tolerances
• Slotted drive accommodates standard flathead screwdrivers

Compatibility

Designed as a general-purpose 1/4-20 UNC machine screw suitable for standard tapped holes and threaded inserts requiring a pan head fastener with a 1/2 inch length under head.

Installation Notes

This fastener is installed by hand-threading into a pre-tapped hole or a nut before tightening with a flathead screwdriver. De-energize all electrical equipment and relieve system pressure before accessing any panel or enclosure where fasteners are being replaced. Avoid over-torquing into thin sheet metal or plastic standoffs, as the 1/4-20 UNC thread can strip shallow threads in soft substrates. Follow applicable NEC or equipment manufacturer guidelines when securing electrical enclosure hardware.
