Value Collection 63546 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 63546 is a hex socket cap screw designed for secure fastening in applications that demand corrosion resistance and reliable clamping force. Threaded at 1/2-13 UNC, it accepts a 3/8-inch hex key drive and provides a length under head of 1.5 inches. The fastener is machined from 316 stainless steel, a material grade well suited to wet, chemical, or marine environments where standard carbon steel would corrode. Machinists, millwrights, maintenance technicians, and industrial tradespeople use this type of screw when a flush or recessed fastener head is required and torque must be applied with an Allen or hex driver.

This screw fits a wide range of industrial, mechanical, and structural assembly tasks. It is commonly used in equipment mounting, machine guarding, bracket fastening, and general maintenance where a 1/2-13 UNC threaded hole is present. The 316 stainless steel construction makes it a strong choice for food-processing equipment, marine hardware, chemical handling systems, and outdoor enclosures where fastener integrity under exposure is critical. The hex socket drive allows use in confined spaces where a wrench cannot swing freely.

Key Features

• 1/2-13 UNC thread size for broad compatibility with standard tapped holes
• 1.5-inch length under head provides solid thread engagement in typical plate and bracket applications
• 3/8-inch hex socket drive accepts standard Allen keys and hex bit drivers
• 316 stainless steel construction resists corrosion in wet, marine, and chemical environments
• Recessed socket head allows flush or countersunk installation in tight clearance areas

Compatibility

Designed as a standard replacement or maintenance fastener for any application requiring a 1/2-13 UNC hex socket cap screw with a 1.5-inch length under head in 316 stainless steel.

Installation Notes

Installation is performed with a 3/8-inch hex key or Allen bit driver. Ensure the mating threaded hole is clean and free of debris before driving the fastener. Apply appropriate thread lubricant or anti-seize compound when installing stainless steel fasteners into stainless or aluminum threads to prevent galling. Do not exceed the rated torque range for 1/2-13 UNC stainless steel fasteners as specified by your application engineering standards.
