Value Collection KP24888 Hex Head Cap Screw 316 Ss 5-pack

Product Description

The VALUE COLLECTION KP24888 is a partially threaded hex head cap screw sized 1-8 x 2-3/4 inches, manufactured from Grade 316 stainless steel with a bright uncoated finish. The UNC thread standard and partial threading make this fastener suited for applications requiring a secure clamping grip between the unthreaded shank and the mating material. Grade 316 stainless provides elevated corrosion resistance compared to standard 304 alloys, making it a practical choice where moisture, chemicals, or saltwater exposure is a concern. Each package contains 5 screws. Plumbers, marine contractors, HVAC technicians, and industrial maintenance professionals commonly use this fastener type in corrosive or wet service environments.

This hex head cap screw is used across a range of trade and industrial applications including plumbing equipment mounting, HVAC component assembly, pool and spa mechanical installations, and marine or coastal structural work. The 1-8 UNC thread form is a coarse-pitch designation widely used in North American trade work for metal-to-metal and metal-to-substrate fastening. The 2-3/4-inch length under head accommodates thicker material stacks where a shorter fastener would not achieve adequate engagement. Sold in a pack of 5 to support small-quantity service and repair jobs.

Key Features

• Grade 316 stainless steel construction for superior corrosion and chemical resistance
• Partially threaded shank provides improved clamping force in bolted joints
• UNC (Unified Coarse) thread standard for broad compatibility with standard tapped holes and nuts
• Bright uncoated finish — no plating to flake or delaminate in wet service conditions
• Inch measurement system: 1-8 thread size, 2-3/4 inches length under head
• Pack of 5 for small-volume service, repair, and maintenance jobs

Compatibility

Designed for use in standard 1-8 UNC tapped holes and with 1-inch UNC hex nuts in inch-system fastener applications. Suitable as a direct replacement in any application calling for a 1-8 x 2-3/4-inch partially threaded hex cap screw in 316 stainless steel.

Installation Notes

Installation should be performed by a qualified tradesperson using an appropriately sized wrench or socket driver rated for the fastener diameter. Always verify that the mating thread or tapped hole is clean and free of debris before installation. In corrosive or wet environments, inspect threads for galling before torquing, as stainless steel fasteners are susceptible to galling under high friction; applying an anti-seize compound is standard practice. Follow applicable mechanical and structural codes for the specific installation type.
