Value Collection R63003328 Hex Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION R63003328 is a hex socket cap screw designed for secure, high-strength fastening in applications where a flush or recessed drive is required. Threaded at 5/16-18 UNC, it features a 1-inch length under head and accepts a 1/4-inch hex (Allen) drive. The screw is manufactured from 316 stainless steel, which provides strong resistance to corrosion and is well-suited for use in wet, marine, or chemically exposed environments. Machinists, millwrights, maintenance mechanics, and assembly technicians regularly specify this fastener for equipment fabrication and structural assemblies.

This fastener is appropriate for general industrial and mechanical applications requiring a 5/16-18 UNC thread. The 316 stainless steel material makes it a practical choice for outdoor installations, food-processing equipment, marine hardware, and any setting where resistance to oxidation and chemical exposure is a priority. It is sold in multiples of 10 units per order, with a package quantity of 1.

Key Features

• 316 stainless steel construction for superior corrosion resistance in harsh or wet environments
• 5/16-18 UNC thread for compatibility with standard coarse-thread fastener applications
• 1-inch length under head provides reliable grip depth for typical structural connections
• 1/4-inch hex socket drive allows torque application with standard Allen keys or hex bit drivers
• Recessed socket head design seats flush or below surface level, reducing snag hazards

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw replacement or new-installation fastener for industrial machinery, structural assemblies, and equipment panels requiring a 316 stainless steel, coarse-thread socket head fastener.

Installation Notes

Installation requires a 1/4-inch hex key or matching bit driver. Always confirm the mating thread is 5/16-18 UNC before installation to avoid cross-threading. Shut down and de-energize any equipment before fastener service on electrical or mechanical assemblies. Follow applicable machine guarding and torque specifications per the equipment manufacturer or applicable ASME standards.
