Value Collection 592155PR Hex Socket Cap Screw 6-40 Unf

Product Description

The VALUE COLLECTION 592155PR is a hex socket cap screw engineered for precision fastening in mechanical, industrial, and trade applications. Featuring a 6-40 UNF thread size, this screw measures 0.75 inches in length under the head and is driven with a 7/64 inch hex key. It is fully threaded from the base of the head to the tip, ensuring maximum thread engagement across the full fastened length. Constructed from 18-8 austenitic stainless steel (Grade A2), it delivers solid corrosion resistance for use in environments where standard carbon steel fasteners would be unsuitable. HVAC, plumbing, and mechanical contractors commonly reach for this type of fastener when securing equipment panels, brackets, and assemblies.

This screw suits a wide range of light-duty mechanical and structural fastening tasks encountered in residential and commercial trade work. The 6-40 UNF thread form is a fine-pitch unified thread used in precision assemblies, instrument panels, and compact equipment housings where vibration resistance and tight tolerances are required. The hex socket drive allows torque application in confined spaces where a standard hex head wrench cannot reach. This item is sold individually but is subject to a minimum order quantity of 100 pieces per order.

Key Features

• 6-40 UNF fine-pitch thread for precision thread engagement and vibration resistance
• Fully threaded design maximizes engagement along the entire 0.75 inch shank length
• 7/64 inch hex socket drive allows use in tight or recessed installation spaces
• 18-8 austenitic stainless steel construction provides corrosion resistance in wet or humid environments
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards
• Grade A2 material grade suitable for general-purpose stainless fastening applications

Compatibility

Designed as a standard 6-40 UNF hex socket cap screw for use in mechanical assemblies, equipment panels, and precision fastening applications requiring an 18-8 stainless steel fully threaded fastener conforming to ASME/ANSI B18.3 and ASTM F837.

Installation Notes

A 7/64 inch hex key or hex bit driver is required for installation. Ensure mating threads are clean and free of debris before driving to avoid galling, which is common with stainless steel fasteners. Do not overtighten stainless steel screws, as the material is susceptible to thread galling under excessive torque. Installation should follow applicable mechanical codes and equipment manufacturer torque guidelines where specified.
