Value Collection R56002160 1/4-20 Machine Screw Round Head

Product Description

The VALUE COLLECTION R56002160 is a 1/4-20 UNC machine screw in a round head, slotted drive configuration. It is manufactured from Grade 316 stainless steel with a bright, uncoated finish. The screw measures 1-1/2 inches in length, measured from under the head. Grade 316 stainless offers strong corrosion resistance, making this fastener suitable for environments exposed to moisture, chemicals, or salt air. This screw is a standard inch-system fastener installed by millwrights, pipefitters, electricians, HVAC technicians, and general maintenance professionals in both light and heavy-duty applications.

This fastener is appropriate for use in residential, commercial, and industrial settings where a 1/4-20 UNC thread pattern is required. The round head profile provides a low-profile, finished appearance on exposed surfaces. The slotted drive accommodates a standard flat-blade screwdriver. Grade 316 stainless is commonly specified in marine, food service, chemical processing, and outdoor environments where standard 304 stainless or carbon steel would be insufficient.

Key Features

• 1/4-20 UNC thread size for compatibility with standard inch-system tapped holes and nuts
• 1-1/2 inch length under head for precise depth control in assembly applications
• Grade 316 stainless steel construction for superior corrosion and chemical resistance
• Round head profile delivers a clean, finished appearance on exposed fastener locations
• Slotted drive accepts standard flat-blade screwdrivers and bits
• Bright, uncoated finish — no plating to chip, flake, or introduce galvanic incompatibility

Compatibility

Designed as a standard inch-system machine screw for use with any 1/4-20 UNC tapped hole, threaded insert, or hex nut. No washer included; sold without washer as specified.

Installation Notes

This fastener is installed using a flat-blade screwdriver or slotted bit driver. Before installation, confirm the mating thread is 1/4-20 UNC and that Grade 316 stainless is compatible with the base material to avoid galvanic corrosion. Apply thread lubricant or anti-seize compound when fastening into stainless or aluminum to prevent galling. Do not overtighten — stainless fasteners are susceptible to galling under excessive torque without lubrication.
