Hertel CH-SA-38300 Spindle Retainer Flanged Washer 3/8-16

Product Description

The HERTEL CH-SA-38300 is a flat-tip clamp spindle retainer with a flanged washer design, built for securing workholding spindle assemblies in machining and fixturing applications. Manufactured from carbon steel with a zinc finish coating, this retainer resists corrosion and provides durable clamping performance. It accepts a 3/8 inch spindle diameter, features a 3/8-16 thread size, and measures 3 inches in overall length. The flanged washer configuration distributes clamping load evenly across the spindle face. This hardware is typically installed by machinists, toolroom technicians, and maintenance personnel working with modular workholding or fixture clamping systems.

The CH-SA-38300 is suited for use in production machining environments, tool and die shops, and general industrial fixturing setups. It fits applications where a flat-tip spindle retainer with a flanged washer is required for standard 3/8-16 threaded spindle assemblies. Sold as an individual unit, it is a direct replacement or spare component for compatible clamping systems that specify this thread and spindle diameter combination.

Key Features

• Flat tip design for direct contact clamping on spindle face
• Flanged washer configuration for improved load distribution
• 3/8-16 thread size for compatibility with standard threaded spindle assemblies
• Carbon steel construction for strength under clamping loads
• Zinc finish coating for corrosion resistance in shop environments
• 3 inches overall length to suit standard fixture depth requirements

Compatibility

Designed as an OEM-style replacement spindle retainer for workholding and fixture clamping assemblies requiring a 3/8 inch spindle diameter and 3/8-16 thread specification.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Disengage and lock out all machine power and relieve any clamping pressure before removing or replacing spindle retainer hardware. Use appropriately sized hand tools for the 3/8-16 thread; avoid over-torquing, which can damage the spindle or washer flange. Verify thread engagement and seating before returning the fixture to service.
