Jergens 39903 Speed Handle 2 Offset Arms 1/2-13

Product Description

The JERGENS 39903 is a two-arm offset speed handle designed for fast, ergonomic hand-tightening and loosening of threaded fasteners in fixturing, tooling, and machine setups. The handle features a tapped 1/2-13 hole, allowing direct threading onto standard bolts, studs, and clamping screws. Constructed from aluminum with a mill finish, the 39903 is lightweight yet durable enough for repeated industrial use. The hub measures 1.125 inches in diameter with a hub height of 1 inch and an overall height of 1.5 inches. The offset arm configuration provides clearance and improved torque leverage in tight workholding applications.

This speed handle is suited for use in manufacturing, machining, and assembly environments where quick manual adjustment of clamping screws, jig fixtures, or tooling components is required. The tapped 1/2-13 thread accommodates a common fastener size found in standard workholding and fixture hardware. Installation is straightforward and does not require additional tooling beyond the fastener it mates to. Machinists, tool and die technicians, and industrial maintenance professionals are the typical end users for this type of handle.
