De-sta-co 036-630-01 Swing Clamp Arm Aluminum 5/16-18

Product Description

The DE-STA-CO 036-630-01 is a single-arm swing clamp arm used in pneumatic or hydraulic workholding fixtures on production lines, jigs, and fixture plates. The arm is machined from aluminum, keeping weight low while providing adequate clamping force for light-to-medium duty fixturing. It measures 3.1 inches in overall arm length and 0.75 inches in arm width, with a 5/16-18 port thread for attachment to a matching swing clamp cylinder body. The clamping height adjusts from 0.38 inches minimum to 0.75 inches maximum, making it suitable for securing workpieces with moderate stack height variation.

This arm is intended for use in manufacturing, assembly, and machining environments where swing clamp cylinders are mounted in fixture plates or tombstones. It fits standard swing clamp cylinder bodies with a 5/16-18 port thread. The single-arm, standard-length configuration is the most common setup for general fixturing where clearance above the workpiece is limited and a single-sided hold-down is preferred over a double-arm design.

Key Features

• Aluminum construction reduces fixture weight without sacrificing dimensional stability
• 5/16-18 port thread size matches common swing clamp cylinder bodies
• Adjustable clamping height range of 0.38 inches to 0.75 inches accommodates workpiece variation
• 3.1 inch arm length provides standard reach for most fixturing layouts
• Single-arm design suits applications requiring one-sided workpiece hold-down

Compatibility

Designed as an OEM-style replacement or spare swing clamp arm for swing clamp cylinder assemblies accepting a 5/16-18 port thread connection.

Installation Notes

Installation is typically performed by a fixture builder, toolmaker, or machinist. Disengage all pneumatic or hydraulic pressure to the swing clamp cylinder before removing or installing the arm. Verify thread engagement is complete and that the arm swings freely through its arc without interference before returning the fixture to service. Follow applicable machine guarding and lockout/tagout procedures per OSHA 1910.147 during service.
