The VALUE COLLECTION R40666133 is a hex socket cap screw designed for fastening applications that require a low-profile, high-strength threaded connection. Manufactured from 18-8 stainless steel, this fastener delivers solid corrosion resistance in both indoor and outdoor service environments. The screw uses a 6-32 UNC thread form and measures 1.75 inches under the head, making it well suited for medium-depth threaded assemblies. Drive engagement is through a 7/64 inch hex socket, which requires an Allen key or hex bit driver for installation. Electricians, HVAC technicians, plumbers, and general trade professionals use cap screws of this type when securing panels, brackets, enclosures, and equipment covers where tool clearance is limited and a flush or recessed fastener head is needed.
This screw is appropriate for light- to medium-duty fastening tasks across residential and commercial service work. Common applications include securing electrical enclosure panels, HVAC equipment access covers, plumbing bracket assemblies, and light structural connections where stainless steel is specified for corrosion resistance or cleanliness requirements. The 18-8 stainless steel grade is widely used in environments exposed to moisture, mild chemicals, or food-adjacent conditions. This part is sold individually but carries a minimum order quantity of 100 units, making it suitable for stocking in a trade supply inventory or for production-volume fastener applications.
Designed as a standard hex socket cap screw for use in any application calling for a 6-32 UNC threaded fastener with an internal hex drive and stainless steel construction.
Installation requires a 7/64 inch Allen key or hex bit driver; confirm the tapped hole or nut thread matches the 6-32 UNC specification before driving. De-energize any electrical equipment and relieve system pressure before accessing panels or enclosures secured with these fasteners. Avoid over-torquing stainless steel fasteners, as the material is susceptible to galling when driven dry; apply an appropriate anti-seize compound when specified by the equipment manufacturer. Follow applicable NEC, IFGC, or IPC guidelines for any fastener used in code-governed installations.
