Value Collection SCIX0-40056-100BX Hex Socket Cap Screw 4-40

Product Description

The VALUE COLLECTION SCIX0-40056-100BX is a hex socket cap screw designed for threaded fastening applications requiring a compact drive profile and corrosion-resistant construction. Built to 4-40 UNC thread specifications, this fastener measures 9/16 inches in length under the head and is fully threaded from tip to head. The 3/32-inch hex drive accepts a standard Allen key or hex driver. Constructed from 18-8 stainless steel with a bright uncoated finish, this screw resists oxidation and is well suited for applications where moisture or chemical exposure is a concern. Sold in a box of 100 units.

This fastener is appropriate for light-duty mechanical assemblies, instrumentation panels, electrical enclosures, HVAC control boards, and general precision equipment requiring a small-diameter machine screw with reliable thread engagement. The 4-40 UNC thread form is a standard designation in light-gauge and thin-material fastening, commonly used in panel-mount and component-level assembly work across HVAC, electrical, and plumbing equipment manufacturing and field service.

Key Features

Compatibility

Designed as a standard 4-40 UNC hex socket cap screw for use in any application requiring this thread form and a 9/16-inch fastener length under head.

Installation Notes

Install using a 3/32-inch hex key or hex bit driver; do not use a driver that does not seat fully in the socket, as this can damage the drive recess. De-energize any electrical or mechanical assembly before fastener replacement or service. Apply only hand-torque appropriate for a 4-40 fastener to avoid stripping threads in soft or thin parent material. Stainless-on-stainless thread galling is possible — apply appropriate anti-seize compound when threading into stainless tapped holes.
