Value Collection 588693PS 1/4-20 X 5-1/2 Round Head Phillips Screw

Product Description

The VALUE COLLECTION 588693PS is a 1/4-20 threaded machine screw with a round head and Phillips drive, manufactured from steel with a zinc finish. It measures 5-1/2 inches in length under the head and is produced to ASME B18.6.3 and SAE J82 standards, ensuring consistent thread form, head geometry, and dimensional tolerances. At 0.06 pounds per unit, it is a standard inch-series fastener suited for general mechanical assembly work. Zinc plating provides a basic level of corrosion resistance for indoor and light-duty outdoor applications. This screw is installed by machinists, millwrights, HVAC technicians, electricians, and general maintenance trades wherever a 1/4-20 threaded fastener is specified.

This fastener is used in a wide range of light industrial, commercial, and residential assembly applications. The 1/4-20 thread is one of the most common coarse-thread sizes in inch-series fastener work, appearing in equipment panels, enclosures, brackets, HVAC components, electrical boxes, and general mechanical assemblies. The round head profile sits above the mating surface and the Phillips drive is compatible with standard power and hand tools. This screw ships as a single unit with a minimum order quantity of 10 pieces.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• 5-1/2 inch length under head accommodates deeper through-hole and stacked-material installations
• Round head profile with Phillips drive for use with common hand and power drivers
• Steel construction with zinc finish for basic corrosion resistance in light-duty service
• Meets ASME B18.6.3 and SAE J82 dimensional and material standards
• Without washer face — installs directly against the mating surface

Compatibility

Designed for use in any application requiring a 1/4-20 UNC machine screw with a round head Phillips drive in the inch measurement system. Suitable for general mechanical, electrical, and HVAC assembly where ASME B18.6.3 compliant fasteners are specified.

Installation Notes

Install using a Phillips screwdriver or a Phillips bit in a power driver sized for a No. 2 or No. 3 tip as appropriate for the application. Ensure the mating tapped hole or nut is the correct 1/4-20 UNC thread form before installation. Do not overdrive — Phillips drive fasteners are susceptible to cam-out under excessive torque. Follow applicable codes and equipment manufacturer guidelines for fastener torque and thread engagement requirements.
