Value Collection 583883PS Machine Screw 3/8-16 X 3.5 in Round Head

Product Description

The VALUE COLLECTION 583883PS is a round-head slotted machine screw designed for general-purpose mechanical fastening in metal assemblies, fixtures, and structural connections. It is threaded 3/8-16 UNC and measures 3.5 inches under the head, providing substantial grip length for thick stock or stacked material. The alloy steel construction delivers high tensile strength, and the zinc finish provides basic corrosion resistance in dry to mildly humid environments. Installation requires a standard flat-blade screwdriver or a matching slotted bit. This screw is sized for applications where a round, low-profile head is preferred over a hex or flat-head fastener.

This screw is suited for light industrial, mechanical, and maintenance applications where a coarse-thread UNC fastener is required. Typical uses include machine assembly, equipment mounting, panel attachment, and general metalwork. The 3/8-16 UNC thread pattern is one of the most common coarse-thread sizes in inch-standard mechanical work and is compatible with standard 3/8-16 tapped holes and nuts. This SKU is sold as a single screw with a minimum order quantity of 50 pieces.
