Value Collection 7-SFM-25C-150 1/4-20 Flat Head Screw

Product Description

The VALUE COLLECTION 7-SFM-25C-150 is a brass flat head slotted machine screw sized 1/4-20 x 1.5 inches overall length. It features a flat head profile with a slotted drive and is manufactured to ASME B18.6.3 dimensional standards. This fastener is used in light mechanical assemblies, electrical enclosures, panel work, and general trade applications where a flush or countersunk head is required. The brass construction provides corrosion resistance and electrical non-conductivity, making it suitable for applications where steel fasteners are not appropriate. Licensed tradespeople and maintenance technicians install this type of fastener across HVAC, electrical, and plumbing panel work.

This screw is appropriate for residential and light commercial trade applications. It is commonly used in electrical panel assemblies, HVAC equipment covers, plumbing access panels, and general equipment mounting where a flush-sitting fastener is needed. The 1/4-20 thread pitch is a standard unified coarse thread and mates with standard 1/4-20 tapped holes or nuts. No washer is included or required under the head for standard countersunk installations. This fastener ships in multiples of 10 per order requirement.

Key Features

• Flat head profile seats flush in countersunk holes for a clean, low-profile finish
• Slotted drive compatible with standard flathead screwdrivers
• Brass material provides corrosion resistance and non-magnetic properties
• Manufactured to ASME B18.6.3 dimensional standards
• 1/4-20 unified coarse thread for broad compatibility with standard tapped holes and nuts
• No washer style — head seats directly against the mating surface

Compatibility

Designed as a standard 1/4-20 flat head slotted machine screw for use in any application requiring an ASME B18.6.3 compliant brass fastener with a countersunk head profile.

Installation Notes

Installation requires a standard flathead screwdriver sized to the slot width. Ensure the mating hole is properly countersunk to the correct angle to allow the flat head to sit flush. Do not overtighten brass fasteners, as brass is softer than steel and the head slot or threads may strip under excessive torque. Confirm thread engagement depth is sufficient in the tapped hole or use a standard 1/4-20 nut on the back side for through-bolt applications.
