Jergens 40303 Speed Handle 2 Offset Arms Cast Iron

Product Description

The JERGENS 40303 is a two-arm offset speed handle designed for rapid manual actuation of threaded fasteners and clamping fixtures. It features a tapped 1/2-13 hole for direct engagement with standard threaded hardware. Cast from iron with a mill finish, this handle delivers the grip leverage and durability required in production and tooling environments. The hub measures 1-1/8 inches in diameter and 1 inch in height, with an overall handle height of 1.5 inches. Two offset arms provide a balanced spinning motion that reduces wrist fatigue during repeated tightening and loosening cycles. It is sized for use as a stand-alone actuation component on jigs, fixtures, and clamping assemblies.

This speed handle is suited for use in industrial, machining, and assembly applications where fast manual adjustment is needed. It threads directly onto 1/2-13 fasteners and is a standard replacement or upgrade for manual actuation points on tooling plates, drill jigs, work-holding fixtures, and similar equipment. Machinists, toolmakers, and assembly technicians are the primary installers. It is appropriate for both light production and maintenance environments where repeated hand operation is part of the workflow.

Key Features

• Tapped 1/2-13 hole for direct threading onto standard fasteners
• Two offset arms for smooth, balanced spinning action and reduced hand fatigue
• Cast iron construction for rigidity and long service life
• Mill finish provides a clean, uncoated surface suitable for most shop environments
• Compact 1.5-inch overall height fits space-constrained fixture layouts
• 1-1/8-inch hub diameter with 1-inch hub height for stable seating

Compatibility

Designed as an OEM-style replacement or direct-fit speed handle for tooling fixtures and clamping assemblies using 1/2-13 threaded hardware.

Installation Notes

Installation is performed by machinists or toolmakers in standard shop conditions. Thread the handle onto the mating 1/2-13 stud or fastener by hand until fully seated before applying final torque by grip. Ensure the mating thread is clean and free of debris prior to installation. De-energize or clamp down any associated machinery before servicing fixtures that incorporate this handle.
