Value Collection C57500306 Machine Screw 1/4-20 X 4 in

Product Description

The VALUE COLLECTION C57500306 is a 1/4-20 UNC machine screw designed for general fastening applications across a wide range of industries and trade work. It features a round head profile with a slotted drive and is manufactured from 18-8 stainless steel with a bright, uncoated finish. The 4-inch length is measured under the head. This screw ships without a washer and conforms to inch-standard measurements. It is well suited for use in mechanical assemblies, equipment mounting, and structural fastening tasks where corrosion resistance is a priority.

This machine screw is commonly used in HVAC equipment assembly, plumbing fixture mounting, electrical enclosure work, and general mechanical installations. The 18-8 stainless steel construction makes it appropriate for both indoor and outdoor environments where mild to moderate corrosion exposure is expected. Technicians and tradespeople typically use these screws when assembling or repairing equipment panels, brackets, and housings that require a standard UNC thread pattern.

Key Features

• 1/4-20 UNC thread size for broad compatibility with standard inch-thread hardware
• 4-inch length under head for deeper fastening reach in thick stock or stacked assemblies
• Round head profile provides a low-profile bearing surface without a washer
• Slotted drive compatible with standard flat-blade screwdrivers
• 18-8 stainless steel construction resists corrosion in wet or outdoor environments
• Bright, uncoated finish maintains dimensional accuracy and clean appearance

Compatibility

Designed as a standard inch-series UNC machine screw suitable for use with any 1/4-20 threaded nut, insert, or tapped hole in mechanical, electrical, and trade applications.

Installation Notes

Installation is typically performed by any trade professional or technician using a flat-blade screwdriver or slotted bit driver. Always ensure the receiving thread is clean and free of debris before driving to avoid cross-threading. When fastening into equipment near live electrical components, de-energize the system and follow all applicable NEC or local electrical codes before beginning work.
