Value Collection R68449644 Hex Socket Cap Screw 3/4-10

Product Description

The VALUE COLLECTION R68449644 is a hex socket cap screw designed for high-strength fastening applications across mechanical, structural, and industrial assemblies. Threaded at 3/4-10 UNC with a 1-1/2 inch length under head, it accepts a 5/8 inch hex drive key for positive torque engagement. Constructed from 18-8 stainless steel, it offers reliable corrosion resistance in wet, chemical-exposed, or outdoor environments. This fastener is suited for use by machinists, millwrights, maintenance mechanics, and contractors who require dimensional accuracy and material consistency in threaded fasteners.

This cap screw is commonly used in equipment fabrication, pump and motor mounting, structural bracketing, and general mechanical assembly where a low-profile socket head and flush or recessed installation is preferred over a hex bolt. The 3/4-10 UNC coarse thread profile allows for fast assembly and is well suited to applications with mild vibration. The 18-8 stainless steel grade provides adequate corrosion resistance for most commercial and light industrial environments without the need for platings or coatings.

Key Features

• 3/4-10 UNC coarse thread for fast engagement and broad compatibility with standard tapped holes
• 1-1/2 inch length under head for accurate reach in standard through-hole and blind-hole applications
• 5/8 inch hex socket drive for use with standard Allen keys and socket drive tools
• 18-8 stainless steel construction provides corrosion resistance without additional surface treatment
• Socket cap head profile allows installation in recessed or tight-clearance locations

Compatibility

Designed as a standard-dimension socket cap screw for use in any application requiring a 3/4-10 UNC threaded fastener with a 1-1/2 inch length under head and 5/8 inch hex drive.

Installation Notes

Installation is performed using a 5/8 inch hex key or socket drive tool. Ensure the mating threaded hole or nut is clean and free of debris before installation. When threading into aluminum or softer base materials, avoid overtorquing to prevent thread stripping. Stainless steel fasteners are susceptible to galling during installation — applying an anti-seize compound to the threads is recommended practice for stainless-to-stainless assemblies.
