Value Collection W55786PS 1/4-20 X 1-1/4 in Pan Head Screw

Product Description

The VALUE COLLECTION W55786PS is a 1/4-20 UNC pan head machine screw designed for general fastening applications where corrosion resistance is required. It measures 1-1/4 inches in length under the head and features a Phillips drive. Manufactured from Grade 316 stainless steel with a bright, uncoated finish, this screw offers strong resistance to corrosive environments including marine, chemical, and outdoor exposure. It is suited for use by maintenance technicians, mechanical contractors, and tradespeople who need a reliable, corrosion-resistant threaded fastener for metal-to-metal or metal-to-substrate assemblies.

This screw is appropriate for use in HVAC equipment panels, electrical enclosures, plumbing fixture mounting, and similar trade applications where moisture or chemical exposure may be present. The 1/4-20 UNC thread is one of the most common coarse-thread sizes in trade work, making this fastener a practical stock item for service vans and shop inventories. The pan head profile provides a low-profile bearing surface suitable for clearance holes in sheet metal and fabricated brackets.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance compared to Grade 304
• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• Pan head profile provides a flat bearing surface with a rounded top
• Phillips drive for use with standard hand and power drivers
• Bright, uncoated finish — no plating to chip, flake, or introduce galvanic risk with stainless hardware
• No washer — clean installation where a separate washer is not required

Compatibility

Designed as a standard 1/4-20 UNC pan head machine screw for use in any application requiring a 1/4-20 coarse-thread fastener with a pan head profile and Phillips drive.

Installation Notes

Installation requires a Phillips screwdriver or Phillips-bit driver sized to match the screw head. Always pre-verify the receiving thread is tapped or fitted with a compatible 1/4-20 nut before driving. Apply appropriate thread lubricant or anti-seize compound when fastening stainless steel to stainless steel components to prevent galling. Follow applicable mechanical codes and equipment manufacturer torque guidance when securing panels or structural components.
