Value Collection 3RSMSR04C010 4-40 X 5/8 in Round Head Screw

Product Description

The VALUE COLLECTION 3RSMSR04C010 is a 4-40 x 5/8 inch round head slotted machine screw manufactured from brass. It is designed for general-purpose fastening applications where corrosion resistance, conductivity, or non-magnetic properties are required. The 4-40 thread designation follows the Unified National Coarse standard, and the screw is produced to ASME B18.6.3 dimensional requirements. Length is measured under the head at 5/8 inches. The slotted drive accepts a standard flat-head screwdriver. These screws are typically installed by electricians, HVAC technicians, equipment assemblers, and maintenance trades working with light-gauge metal or plastic assemblies.

This screw is suited for residential and commercial applications involving control panels, enclosures, terminal boards, and small mechanical assemblies. The brass construction makes it a common choice where steel fasteners are not appropriate due to corrosion exposure, electrical conductivity requirements, or contact with dissimilar metals. Sold in a minimum order quantity of 100 pieces per order, with a package quantity of 1.

Installation Notes

Install using a flat-head screwdriver sized to match the slotted drive to avoid cam-out and head damage. De-energize any electrical panel or equipment before fastening or removing screws in live enclosures. Brass fasteners are softer than steel; avoid overtightening to prevent thread stripping or head deformation. Follow applicable equipment manufacturer torque guidelines and NEC requirements when used in electrical assemblies.
