Value Collection R40634443 Hex Socket Cap Screw 0-80 Unf

Product Description

The VALUE COLLECTION R40634443 is a 0-80 UNF hex socket cap screw designed for precision fastening applications requiring a fine thread profile and compact drive geometry. The screw measures 3/8 inch in length under the head and is driven by a hex socket tool. Constructed from 18-8 stainless steel, it resists corrosion in wet, chemical-exposed, and marine environments. This fastener is suited for tight-clearance assemblies where a low-profile socket head is necessary and thread integrity under vibration is a priority.

This screw is used in light mechanical, instrumentation, and precision equipment assemblies where a 0-80 UNF thread pitch is specified. Typical applications include instrument panels, electronic enclosures, optical equipment, and small-scale mechanical subassemblies. The stainless steel construction makes it appropriate for indoor and outdoor service environments where mild corrosion resistance is required. Technicians working on precision equipment or control panel fabrication are the primary installers of this fastener.

Key Features

• 0-80 UNF thread for fine-pitch, high-precision fastening in small assemblies
• 3/8 inch length under head suits shallow-stack and thin-panel applications
• 18-8 stainless steel construction provides corrosion resistance without plating
• Hex socket drive allows torque application in confined clearance areas
• Cap screw head style provides a clean bearing surface and controlled clamping load

Compatibility

Designed as a standard 0-80 UNF hex socket cap screw for use in any assembly or component that calls out a 0-80 UNF thread, 3/8 inch length under head, and hex socket drive in stainless steel.

Installation Notes

Install using the correct hex key or Allen-type driver sized for a 0-80 socket head to avoid rounding the drive recess. Apply consistent, controlled torque appropriate for the 18-8 stainless steel material and the mating thread material to prevent galling. Stainless fasteners are susceptible to thread galling under excessive speed or torque — use an anti-galling lubricant when installing into stainless or aluminum tapped holes. Verify mating thread class and hole depth before installation.
