Value Collection R57001269 Hex Head Cap Screw 5/8-11x12

Product Description

The VALUE COLLECTION R57001269 is a partially threaded hex head cap screw designed for heavy-duty fastening applications requiring corrosion resistance. Sized at 5/8-11 thread with a 12-inch length under head, this fastener is manufactured from 18-8 stainless steel and left uncoated for a clean metal finish. The UNC (Unified National Coarse) thread standard ensures wide compatibility with standard tapped holes and nuts. At 1.1 pounds, this is a substantial fastener suited for structural and mechanical assemblies where length and material grade matter. Licensed tradespeople and maintenance mechanics reach for this size when joining thick structural members or long-span assemblies.

This fastener is commonly used in industrial equipment, marine hardware, food processing machinery, and general mechanical assemblies where corrosion resistance is a priority. The 18-8 stainless steel construction resists rust and oxidation in wet or chemically active environments. The partial threading is appropriate for applications requiring a smooth shank section to bear shear loads or allow clamping without thread engagement through the full grip length. It is installed with a standard hex wrench or socket in inch sizing.

Key Features

• 5/8-11 UNC thread size for compatibility with standard coarse-thread nuts and tapped holes
• 12-inch length under head provides extended grip for thick or stacked assemblies
• 18-8 stainless steel construction offers corrosion and oxidation resistance
• Partial threading leaves a smooth shank section for shear load bearing and precise clamping
• Uncoated finish maintains material dimensions and avoids coating interference in tight tolerances

Compatibility

Designed as a standard UNC inch-series hex head cap screw compatible with 5/8-11 coarse-thread nuts, inserts, and tapped holes in inch-standard fastening applications.

Installation Notes

Installation is performed by mechanics, millwrights, or maintenance technicians using a hex socket or open-end wrench in the appropriate inch drive size. Always verify that the mating thread is also 5/8-11 UNC before driving to avoid cross-threading. For structural applications, consult applicable fastener torque tables for 18-8 stainless steel to determine proper clamp load. Apply appropriate anti-seize compound on stainless fasteners in high-heat or dissimilar-metal applications to prevent galling.
