Value Collection 199548 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 199548 is a hex socket cap screw designed for secure fastening in applications requiring a recessed drive and a clean, low-profile head. Sized at 1/4-20 UNC with a 2-inch length under head, this screw is partially threaded and driven with a 3/16-inch hex key. It is manufactured from 18-8 stainless steel, offering corrosion resistance suitable for both indoor and outdoor environments. This fastener is used by mechanical contractors, millwrights, equipment technicians, and maintenance professionals across a wide range of trade and industrial applications.

This screw fits general-purpose fastening tasks where a hex socket drive is required and where stainless steel construction is specified for corrosion resistance or cleanliness requirements. The partial threading provides a shoulder effect useful in applications where the unthreaded shank must pass through a clearance hole before engaging the mating thread. Typical installation scenarios include equipment enclosures, brackets, fixtures, and structural assemblies in HVAC, plumbing, and light industrial settings.

Key Features

• 1/4-20 UNC thread size for broad compatibility with standard inch-thread tapped holes
• 2-inch length under head accommodates moderate material stack depths
• Partially threaded shank allows use in through-hole and clearance-fit assemblies
• 3/16-inch hex drive for use with standard hex keys or Allen-type bit drivers
• 18-8 stainless steel construction resists corrosion and oxidation

Compatibility

Designed as a standard inch-series hex socket cap screw suitable for any application with a 1/4-20 UNC tapped hole requiring a 2-inch partially threaded fastener in stainless steel.

Installation Notes

Installation requires a 3/16-inch hex key or matching socket bit driver. Ensure the mating hole is clean and properly tapped to 1/4-20 UNC before installation. Apply appropriate thread lubricant or anti-seize compound if required by the application to prevent galling in stainless-to-stainless assemblies. Follow applicable mechanical or equipment manufacturer torque guidelines for the joint being assembled.
