Value Collection 063016PS Flat Socket Cap Screw 4-40

Product Description

The VALUE COLLECTION 063016PS is a flat socket cap screw designed for precision fastening applications requiring a flush or countersunk finish. Sized at 4-40 x 5/16 inches overall length with a 5/32-inch hex socket drive, this screw features an 82-degree flat head that seats flush with the work surface when properly countersunk. Manufactured from 316 stainless steel, it offers strong corrosion resistance in wet, marine, and chemically exposed environments. Installation requires a 5/32-inch hex key or Allen driver. This fastener follows Unified National Coarse (UNC) thread standards and is suited for light-duty mechanical assemblies where head protrusion is not acceptable.

This screw is commonly used in instrumentation, enclosures, panel fabrication, and light mechanical assemblies across plumbing, HVAC, electrical, and industrial service work. The 316 stainless steel material grade makes it a practical choice in environments with exposure to moisture, chlorides, or mild chemicals. Minimum order quantity is 10 pieces, sold in single-unit packages. Trade professionals use these fasteners when a flush-mount connection point is required on sheet metal panels, brackets, or housings.

Key Features

• 82-degree flat head seats flush in countersunk holes for a low-profile finish
• 316 stainless steel construction provides corrosion resistance in wet and chloride-exposed environments
• 5/32-inch hex socket drive for secure torque transfer with standard Allen keys
• 4-40 UNC thread standard ensures compatibility with common tapped holes in light assemblies
• 5/16-inch overall length suits thin-panel and shallow-depth fastening applications

Compatibility

Designed as a standard UNC-thread flat socket cap screw for use in any application requiring a 4-40 tapped hole and a countersunk 82-degree seating angle.

Installation Notes

Installation requires a properly countersunk 82-degree hole to allow the flat head to seat flush. Use a calibrated 5/32-inch hex key or bit to drive the fastener and avoid cam-out damage to the socket. Do not exceed the fastener's rated load by over-tightening in soft materials. Follow applicable mechanical and electrical codes when fastening panels or enclosures in regulated installations.
