Value Collection 3RSMSF94C012 Machine Screw 1/4-20

Product Description

The VALUE COLLECTION 3RSMSF94C012 is a flat head slotted machine screw designed for general-purpose fastening in mechanical, electrical, and light structural assemblies. Manufactured from brass, this screw features a 1/4-20 unified coarse thread and an overall length of 3/4 inches. The flat head profile sits flush with or below the mating surface when countersunk, making it suitable for applications where a low-profile or flush finish is required. It meets ASME B18.6.3 dimensional standards, ensuring consistent head geometry, thread tolerance, and length accuracy across production runs. Sold in a minimum order quantity of 100 pieces per order.

This screw is appropriate for use in residential and commercial electrical enclosures, HVAC equipment panels, plumbing fixture assemblies, and general sheet metal or machined-component applications where a non-ferrous, corrosion-resistant brass fastener is specified. The slotted drive is compatible with standard flat-blade screwdrivers and is commonly used in environments where magnetic or stainless fasteners are not suitable. The 1/4-20 thread size is a widely used coarse-thread standard, compatible with tapped holes and standard nuts of that designation.

Key Features

• Brass construction provides corrosion resistance and non-magnetic properties
• Flat head design allows flush or countersunk installation in mating surfaces
• Slotted drive accepts standard flat-blade screwdrivers
• 1/4-20 unified coarse thread for broad compatibility with tapped holes and nuts
• Meets ASME B18.6.3 standards for consistent dimensional accuracy
• Overall length of 3/4 inches with length under head of 3/4 inches

Compatibility

Designed as a standard 1/4-20 flat head slotted machine screw per ASME B18.6.3, suitable for use in any application requiring a brass fastener of this thread size, head type, and overall length.

Installation Notes

Installation is performed with a flat-blade screwdriver sized to the slotted drive to avoid cam-out or head damage. When installing into a countersunk hole, ensure the countersink angle matches the flat head geometry to achieve a flush seating surface. Brass is a softer material than steel — avoid overtorquing, which can strip threads or deform the head. Follow applicable mechanical or electrical code requirements for fastener selection when used in listed or code-regulated assemblies.
