Value Collection 1414MSRNH 1/4-20 X 7/8 in Round Head Slotted Screw

Product Description

The VALUE COLLECTION 1414MSRNH is a 1/4-20 unified coarse thread machine screw with a round head and slotted drive, sold in a minimum quantity of 100 pieces. The fastener is manufactured from steel with a zinc finish coating and meets the ASME B18.6.3 and SAE J82 material grade standards. The shank measures 7/8 inches in length under the head. The round head profile provides a low-profile bearing surface suited for general-purpose mechanical assembly. This screw is commonly installed by machinists, millwrights, electricians, and HVAC technicians in light structural and panel-fastening applications.

This machine screw is appropriate for a wide range of general industrial and trade applications including equipment panel assembly, junction box covers, bracket mounting, and other light-duty mechanical connections requiring a standard 1/4-20 coarse thread fastener. It is used in both residential and commercial work where a slotted round head profile is required and no washer is needed. Applications span HVAC cabinet assembly, electrical enclosures, plumbing equipment panels, and general sheet metal or light structural work.

Key Features

• 1/4-20 unified coarse thread for broad compatibility with standard tapped holes and hex nuts
• Round head profile provides a domed, finished appearance with moderate bearing surface
• Slotted drive accommodates standard flat-blade screwdrivers
• Zinc finish provides basic corrosion resistance for indoor and light-duty environments
• Meets ASME B18.6.3 and SAE J82 dimensional and material standards
• Sold in multiples of 100 for job-site and shop inventory use

Compatibility

Designed as a standard 1/4-20 coarse thread machine screw conforming to ASME B18.6.3, compatible with any standard 1/4-20 tapped hole, nut, or threaded insert in that fastener standard.

Installation Notes

Install with a flat-blade screwdriver sized to fit the slot width; an undersized driver will damage the slot and reduce drive torque. Ensure the mating hole is properly tapped to 1/4-20 UNC specification or use with an appropriate hex nut. De-energize any electrical equipment before fastening panels or enclosures in accordance with NFPA 70 lockout procedures. Do not overtighten in thin sheet metal or plastic — check the material's thread engagement depth before final torque.
