Maintain precise axial alignment and maximum leverage when tapping clean, straight threads. Upgrade your machining and thread-repair setup with this used Clarkson Osborn TA45004 Adjustable Tap Wrench.

Engineered for precision machinist work, toolroom maintenance, and heavy industrial thread cutting, the Clarkson Osborn TA45004 Adjustable Tap Wrench provides high clamping force on square tap shanks ranging from 1/4-inch to 3/4-inch capacity. Featuring a classic straight bar handle design, this wrench delivers balanced, two-handed rotational leverage to prevent tap binding and breakage during manual thread-cutting operations.

This item is in excellent, fully functional used condition. The hardened steel v-jaw clamping mechanism closes squarely and smoothly, securing square tap shanks tightly without slippage or rounding. The knurled handle adjusts cleanly along its precision threads with zero binding or slop. Built from heavy-duty forged steel to withstand high manual torque, it displays minor, normal cosmetic shop wear—such as light surface scuffs, faint tool-box scratches, and subtle shop patina—while retaining complete structural integrity.

Key Features & Benefits

  • Wide 1/4" to 3/4" Capacity: Accommodates a broad range of standard hand taps, reamers, and screw extractors with square shanks.

  • Precision V-Jaw Clamping: Hardened tool steel jaws grip square tap shanks securely to eliminate slipping under heavy tapping load.

  • Balanced Straight Bar Design: Dual handle configuration provides uniform rotational force to keep taps square and true to the hole axis.

  • Knurled Adjustable Handle: Textured handle sleeve offers a firm grip for fast jaw adjustments and firm clamping pressure.

  • Industrial Steel Construction: Heavy-duty forged body built for rigorous daily shop use in machining and maintenance operations.
