Value Collection 3RSMSF94C008 Flat Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 3RSMSF94C008 is a 1/4-20 flat head slotted machine screw manufactured from brass. It measures 1/2 inch in overall length and conforms to ASME B18.6.3, the standard governing slotted flat head machine screws in inch dimensions. The flat head profile sits flush with or below the mating surface when installed in a countersunk hole, making it well suited for assemblies where a low-profile fastener is required. This screw is sold in a minimum order quantity of 100 pieces, appropriate for maintenance stock, panel fabrication, or equipment assembly applications where brass fasteners are specified for corrosion resistance or non-magnetic requirements.

This fastener is used across a wide range of light-duty mechanical and electrical assembly work including control panel builds, terminal board mounting, HVAC equipment enclosures, plumbing fixture trim, and general equipment fabrication where a 1/4-20 thread pitch and brass material are called out. The slotted drive accommodates a standard flat-blade screwdriver. No washer is included or required under the head for standard countersunk installations.

Key Features

• 1/4-20 unified coarse thread for broad hardware compatibility
• Flat head profile for flush or below-surface seating in countersunk holes
• Slotted drive accepts standard flat-blade screwdrivers
• Brass construction provides corrosion resistance and non-magnetic properties
• Conforms to ASME B18.6.3 dimensional standard
• Overall length of 1/2 inch equals length under head for flat head geometry

Compatibility

Designed as a standard 1/4-20 x 1/2 inch flat head slotted machine screw per ASME B18.6.3, suitable for use in any application requiring inch-series brass fasteners of this thread size and head style.

Installation Notes

A properly sized countersink must be prepared in the mating material before installation to allow the flat head to seat flush. Use a calibrated flat-blade screwdriver sized to the slot to avoid cam-out and slot damage. Brass is a softer material than steel — avoid excessive torque that can strip threads or deform the head. Confirm thread engagement depth is adequate in the receiving material before applying full drive force.
