Value Collection S674373 Hex Head Cap Screw 3/8-24 X 2 in Grade 8

Product Description

The VALUE COLLECTION S674373 is a 3/8-24 hex head cap screw manufactured from Grade 8 alloy steel with an uncoated finish. It features a 2-inch length under head and a 9/16-inch hex drive. Grade 8 alloy steel provides high tensile strength and hardness, making it suitable for demanding mechanical and structural fastening applications. The UNF (Unified National Fine) thread standard offers tighter thread engagement compared to coarse thread variants, which is advantageous where vibration resistance and precise clamping are required. Licensed trades and maintenance professionals across HVAC, mechanical, and industrial service work rely on this fastener for equipment assembly and structural connections.

This hex head cap screw is suited for residential and commercial mechanical installations where fine-thread fasteners are specified. Typical applications include equipment mounting, bracket assembly, and structural joint fastening in HVAC systems, plumbing equipment supports, and general mechanical assemblies. The Grade 8 rating makes it appropriate for high-load connections where standard Grade 5 hardware would be undersized. Sold in a package quantity of 25, this screw is a practical stocking item for service trucks and shop inventory.

Key Features

• Grade 8 alloy steel construction for high tensile strength in demanding fastening applications
• 3/8-24 UNF thread provides fine-thread engagement for improved vibration resistance
• 2-inch length under head suits medium-depth clamping and through-bolt applications
• 9/16-inch hex drive is compatible with standard hand and power tools
• Uncoated finish — suitable for indoor or protected installations; apply corrosion protection as required by the installation environment
• Package quantity of 25 supports efficient stocking and reduces per-call waste

Compatibility

Designed as a standard 3/8-24 UNF Grade 8 hex head cap screw for use in any application specifying 3/8-24 fine-thread fasteners with a 2-inch grip length under head.

Installation Notes

Installation is performed by licensed mechanical, HVAC, or plumbing technicians as part of equipment assembly or structural fastening work. De-energize and lock out all equipment per applicable safety procedures before replacing or installing fasteners on powered systems. Use calibrated torque tooling appropriate to Grade 8 fastener specifications as defined by the equipment manufacturer or applicable code — do not rely on feel alone when torque is critical. The uncoated finish offers no corrosion protection; apply a suitable coating or use in a dry, protected environment to maintain fastener integrity over time.
