Value Collection R63003642 Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R63003642 is a hex socket cap screw designed for applications requiring a secure, recessed drive fastener in corrosion-resistant material. Threaded 1/4-20 UNC, it has a length under head of 2 inches and is driven by a 3/16-inch hex key. Constructed from 316 stainless steel, this fastener resists corrosion, chemical exposure, and moisture, making it suitable for demanding environments. It is installed by maintenance technicians, mechanical contractors, and trade professionals working on equipment assemblies, brackets, enclosures, and structural connections where a flush or low-profile cap screw is required.

This screw is suited for residential and commercial mechanical, HVAC, plumbing, and electrical panel fabrication work where 1/4-20 UNC threading is specified. The 316 stainless steel grade provides enhanced resistance to chlorides and oxidizing environments compared to standard 304 stainless, making it appropriate for outdoor equipment, coastal installations, and wet-area applications. Technicians use this fastener when assembling equipment frames, securing access panels, or replacing OEM hardware that calls for a 1/4-20 hex socket cap screw.

Key Features

• 1/4-20 UNC thread for wide compatibility with standard tapped holes and threaded inserts
• 2-inch length under head provides adequate thread engagement for typical structural connections
• 3/16-inch hex drive allows use of standard Allen keys and hex bit drivers
• 316 stainless steel construction resists corrosion, moisture, and chemical exposure
• Recessed socket cap head keeps a low profile and allows torque application in confined spaces

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any application specifying this thread size, drive type, and 2-inch under-head length in 316 stainless steel.

Installation Notes

Installation requires a 3/16-inch hex key or Allen-style bit driver. Always verify the tapped hole thread specification matches 1/4-20 UNC before installation. Avoid cross-threading by starting the fastener by hand before applying torque. Do not mix stainless steel fasteners with dissimilar metals in environments where galvanic corrosion is a concern.
