Value Collection KP24862 Hex Head Cap Screw 3/8-16 X 4.5 in

Product Description

The VALUE COLLECTION KP24862 is a partially threaded hex head cap screw designed for bolted assemblies requiring corrosion resistance in demanding service environments. Sized at 3/8-16 UNC thread with a 4-1/2 inch length under head, this fastener is manufactured from Grade 316 stainless steel with a bright, uncoated finish. The partial thread configuration allows the unthreaded shank to bear shear loads while the threaded portion engages the mating nut or tapped hole. Mechanical contractors, plumbers, pipefitters, and industrial maintenance technicians install this type of fastener where exposure to moisture, chemicals, or saltwater environments makes carbon steel unsuitable.

This screw is suited for use in plumbing, HVAC equipment mounting, marine applications, food-processing environments, and chemical plant installations where Grade 316 stainless steel is specified for its molybdenum content and superior chloride resistance. It is appropriate for both indoor and outdoor installations on structural connections, flanged joints, equipment bases, and pipe supports. The 3/8-16 UNC thread is a standard coarse-thread profile compatible with 3/8-16 hex nuts and threaded inserts.

Key Features

• Grade 316 stainless steel construction for strong resistance to chlorides and corrosive media
• Partially threaded shank supports shear load transfer in bolted joints
• 3/8-16 UNC coarse thread for broad compatibility with standard nuts and tapped holes
• 4-1/2 inch length under head accommodates thicker stack-ups and flanged connections
• Bright uncoated finish maintains dimensional consistency without coating buildup on threads

Compatibility

Designed as a standard 3/8-16 UNC partially threaded hex head cap screw compatible with 3/8-16 hex nuts, coupling nuts, and tapped holes conforming to Unified National Coarse thread standards in inch-measurement applications.

Installation Notes

Installation should be performed by a qualified mechanic, pipefitter, or maintenance technician using an appropriately sized hex wrench or socket. Ensure mating threads are clean and free of debris before assembly. For stainless steel fasteners, apply an anti-galling compound to prevent thread seizure during tightening. Always follow applicable mechanical codes and equipment manufacturer guidelines for fastener torque and joint preload requirements.
