Value Collection 583619PR 1/4-20 X 5/8 in Round Head Slotted Screw

Product Description

The VALUE COLLECTION 583619PR is a 1/4-20 UNC machine screw with a round head and slotted drive, manufactured from alloy steel with a zinc finish. The 5/8-inch length is measured under the head, as is standard for round-head fasteners. The zinc coating provides basic corrosion resistance for general interior and light-duty applications. This screw is sold in a minimum quantity of 100 pieces per order, making it appropriate for production, maintenance, and assembly environments where consistent fastener inventory is needed. Licensed tradespeople and maintenance professionals in HVAC, electrical, and plumbing work commonly use this size for panel assemblies, brackets, and equipment mounting.

This screw is suited for light to medium fastening tasks in metal and other materials where a 1/4-20 UNC thread pattern is specified. The round head profile seats flush against flat surfaces without the need for a washer, and the slotted drive allows installation with a standard flathead screwdriver. Typical applications include equipment enclosures, junction box assemblies, and structural brackets in commercial and residential trade work. The alloy steel construction provides adequate tensile strength for mechanical fastening in non-corrosive environments.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• 5/8-inch length under head for precise fitment in shallow-clearance applications
• Round head profile distributes clamping load across the bearing surface
• Slotted drive compatible with standard flathead screwdrivers
• Alloy steel construction with zinc finish for general-purpose use
• Sold in multiples of 100 for production and maintenance stocking

Compatibility

Designed as a general-purpose UNC machine screw for use in any application requiring a 1/4-20 thread, round head, and slotted drive in alloy steel.

Installation Notes

Installation requires a standard flathead screwdriver sized to the slot width; use of an oversized driver can damage the slot and reduce torque transfer. Ensure the mating thread is clean and properly tapped to 1/4-20 UNC specification before driving the screw. De-energize any electrical equipment and relieve system pressure before accessing fastened panels or enclosures. Do not exceed the rated tensile strength of the alloy steel by over-torquing, particularly in thin sheet metal applications.
