Value Collection R63034448 Pan Head Machine Screw 1/4-20

Product Description

The VALUE COLLECTION R63034448 is a 1/4-20 x 1.5-inch pan head slotted machine screw manufactured from grade 18-8 stainless steel with a bright, uncoated finish. Sized at 1/4-20 UNC thread with 1.5 inches of length measured under the head, this fastener delivers solid corrosion resistance in wet, humid, and chemically active environments. The pan head profile provides a wide, low-profile bearing surface, while the slotted drive accommodates standard flathead screwdrivers. Sold in minimum order quantities of 100 pieces, this screw suits trade applications where bulk fastener supply is standard practice.

This screw is well-suited for light mechanical assemblies, HVAC equipment panels, electrical enclosures, plumbing fixtures, and general trade fabrication where a corrosion-resistant fastener is required. The 18-8 stainless steel construction makes it appropriate for indoor and outdoor installations exposed to moisture. The inch-system 1/4-20 UNC thread is one of the most common fastener sizes across HVAC, plumbing, and electrical trades, fitting a wide range of tapped holes and standard nuts.

Key Features

• 1/4-20 UNC inch-system thread — widely compatible across trade applications
• 1.5-inch length under head for consistent grip depth in standard assemblies
• Grade 18-8 stainless steel construction for corrosion resistance in wet environments
• Pan head profile provides broad bearing surface and low-profile seating
• Slotted drive compatible with standard flathead screwdrivers
• Bright, uncoated finish — no additional coating to crack or delaminate over time

Compatibility

Designed as a standard inch-system 1/4-20 UNC machine screw suitable for tapped holes, standard hex nuts, and coupling nuts sized for 1/4-20 thread in residential and light commercial trade assemblies.

Installation Notes

This fastener is installed by general tradespeople, HVAC technicians, plumbers, and electricians using a standard flathead screwdriver or slotted bit driver. Ensure the mating hole is clean and properly tapped to 1/4-20 UNC before driving. Do not overtighten stainless steel fasteners, as the material is susceptible to galling; apply an appropriate anti-seize compound when threading into stainless or aluminum tapped holes. Follow applicable equipment manufacturer torque guidelines when fastening to panels or enclosures.
