Value Collection R63064228 8-32 Flat Head Slotted Machine Screw

Product Description

The VALUE COLLECTION R63064228 is a #8-32 x 5/8-inch flat head slotted machine screw manufactured from grade 18-8 stainless steel. It features a unified coarse (UNC) thread form and a bright, uncoated finish. The flat head profile allows the screw to sit flush with or below the surface of the mating material when countersunk. Overall length is measured from the top of the head to the tip, and the length under the head is also 5/8 inches. This fastener is installed using a standard flat-blade screwdriver or slotted bit driver. It is sold in multiples of 100 per order.

This screw is suited for general mechanical assembly, light fabrication, panel mounting, and equipment enclosure work across industrial, commercial, and trade applications. The 18-8 stainless steel construction provides good corrosion resistance, making it appropriate for environments with moderate moisture exposure. Electricians, HVAC technicians, and plumbers commonly use this size when securing control panels, junction box components, or equipment covers where a flush fastener profile is required.

Key Features

• Grade 18-8 stainless steel construction for corrosion resistance in moderate-moisture environments
• #8-32 UNC thread for reliable engagement with standard tapped holes and hex nuts
• Flat head design allows flush or countersunk installation
• Slotted drive accepts standard flat-blade screwdrivers and slotted power bits
• Bright, uncoated finish with no plating buildup to affect thread tolerances
• Without washer — no integrated washer flange to interfere with countersunk surfaces

Compatibility

Designed as a general-purpose UNC machine screw compatible with standard #8-32 tapped holes, threaded inserts, and hex nuts used in typical mechanical, electrical, and HVAC panel assembly applications.

Installation Notes

Installation requires a properly sized flat-blade screwdriver or slotted insert bit; use of a mismatched driver width risks cam-out and head damage. Ensure the receiving hole is tapped to #8-32 UNC or fitted with an appropriate threaded insert before driving. Do not overtighten stainless steel fasteners into stainless or aluminum materials, as galling can occur — apply an anti-seize compound if code or application requires. De-energize any electrical equipment before securing fasteners inside live enclosures in accordance with NFPA 70E lockout/tagout procedures.
