Value Collection R68449246 Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R68449246 is a hex socket cap screw designed for secure fastening in mechanical, structural, and industrial assemblies. The screw features a 5/8-11 UNC thread size and measures 1.25 inches in length under the head. It is driven by a 0.5 inch hex key and is manufactured from 18-8 stainless steel, giving it solid corrosion resistance in wet, outdoor, or chemically exposed environments. This fastener is suited for applications where a flush or recessed drive head is required and torque must be applied through an internal hex socket rather than an external wrench flat. Machinists, maintenance technicians, pipefitters, and general trade workers install this type of fastener across a wide range of equipment and fabrication work.

This hex socket cap screw is used in light to medium-duty mechanical assemblies, equipment frames, pump housings, pipe supports, and structural brackets where stainless steel corrosion resistance is needed. The 5/8-11 UNC coarse thread pitch is the standard for this diameter and allows for fast engagement in through-hole and tapped applications. The 18-8 alloy grade performs well in mildly acidic, marine, and food-processing environments. It is sold individually and fits standard 0.5 inch hex key or Allen-type drive tools.

Key Features

• 5/8-11 UNC coarse thread for standard tapped-hole compatibility
• 1.25 inches length under head for precise depth engagement
• 0.5 inch internal hex drive for torque application with a hex key or bit driver
• 18-8 stainless steel construction resists corrosion in wet and chemically active environments
• Socket cap head profile allows recessed installation in countersunk or clearance-limited spaces

Compatibility

Designed as a standard 5/8-11 UNC hex socket cap screw for use in any tapped hole or through-hole application requiring this thread size and a 0.5 inch hex drive. Compatible with standard 5/8-11 nuts and threaded inserts.

Installation Notes

Install using a 0.5 inch hex key or Allen-type drive tool. Apply only the torque appropriate for an 18-8 stainless steel fastener at this diameter — consult a standard fastener torque chart for the specific joint material and lubrication condition. Inspect the tapped hole for debris before installation to avoid cross-threading. When used in structural or pressure-containing applications, follow applicable codes and engineering requirements.
