Value Collection 3RSMSF94C208 Flat Head Machine Screw

Product Description

The VALUE COLLECTION 3RSMSF94C208 is a 1/4-20 flat head slotted machine screw manufactured from brass. It measures 2-1/2 inches in overall length and features a countersunk flat head profile that sits flush with or below the surface of the mated material when properly driven. The slotted drive accepts a standard flat-blade screwdriver. Brass construction provides corrosion resistance and is well suited to applications where galvanic compatibility with non-ferrous metals is required. This fastener conforms to ASME B18.6.3 inch-series standards. It is sold individually and must be ordered in multiples of 10.

This screw is used in general mechanical assembly, electrical enclosures, plumbing fixture mounting, and HVAC equipment panels where a flush-seating fastener is needed. Brass is commonly specified in marine, wet, or chemically active environments where steel would corrode. The 1/4-20 unified coarse thread is one of the most common thread forms in inch-series fastener applications, making this screw easy to source mating hardware for across residential and light commercial work.

Key Features

• 1/4-20 unified coarse thread for broad hardware compatibility
• Flat countersunk head seats flush with the mating surface
• Slotted drive accepts standard flat-blade screwdrivers
• Brass material resists corrosion in wet and chemically active environments
• Conforms to ASME B18.6.3 inch-series fastener standard
• No washer — installs directly against the mating surface

Compatibility

Designed for use in any application requiring a 1/4-20 inch-series flat head slotted machine screw. Suitable for use with standard 1/4-20 threaded inserts, nuts, and tapped holes conforming to ASME inch-series thread standards.

Installation Notes

Installation is performed with a flat-blade screwdriver sized to the slot. The receiving material should be tapped to 1/4-20 or fitted with a compatible threaded insert before installation. Countersink the mating hole to the correct angle for a flat head screw to achieve a flush finish. Do not overtighten brass fasteners, as the material is softer than steel and the threads can strip or the head can shear under excessive torque.
