Value Collection 3TSSF910C108 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 3TSSF910C108 is a flat socket cap screw designed for fastening applications that require a flush or countersunk finish. It features a 5/8-11 UNC thread and measures 1-1/2 inches in overall length. The 82-degree flat head seats fully into a countersunk hole, eliminating protrusion above the mating surface. Drive engagement is through a 3/8-inch hex socket, requiring an Allen key or hex bit driver. Constructed from 316 stainless steel, this fastener resists corrosion in wet, chemical, and marine environments. Machinists, millwrights, pipefitters, and maintenance technicians commonly install these in equipment assemblies, process piping supports, and structural fixtures where surface clearance is critical.

This flat socket cap screw is suited for industrial, commercial, and marine applications where a recessed fastener head is required. The 316 stainless steel material grade provides superior chloride and oxidation resistance compared to 304 grade, making it appropriate for outdoor installations, food-processing equipment, chemical handling systems, and coastal environments. The UNC thread form is standard across North American fastener tooling and tapped-hole specifications, simplifying sourcing and replacement in the field.

Key Features

• 82-degree flat head seats flush in countersunk holes to eliminate surface protrusion
• 3/8-inch hex socket drive for secure torque transfer with standard Allen tooling
• 316 stainless steel construction for superior corrosion and chloride resistance
• 5/8-11 UNC thread form compatible with standard North American tapped holes
• 1-1/2-inch overall length suits medium-depth fastening applications

Compatibility

Designed as a standard-specification 5/8-11 UNC flat socket cap screw for use in any countersunk hole application requiring an 82-degree flat head and 316 stainless steel material grade.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 3/8-inch hex key or hex bit driver. Ensure the receiving hole is properly countersunk to 82 degrees for correct head seating before driving the fastener. Apply appropriate anti-seize compound when installing stainless steel fasteners into stainless steel tapped holes to prevent galling. Do not exceed the rated torque for 316 stainless steel fasteners of this diameter, and refer to applicable engineering or equipment specifications for torque requirements.
