Steelman M14-1.50 Metric Split Die Thread Chaser — M14 x 1.50 for Wheel Studs, Split-Die with Indexing Pins

Steelman Professional M14-1.50 split die thread chaser repairs damaged M14-1.50 metric threads while preventing cross-threading by starting the cut behind the ruined section.

When a bolt or wheel stud arrives with damaged threads, a quick, accurate repair saves parts and labor. The Steelman M14-1.50 split die thread chaser is a hand-driven tool built to restore metric threads cleanly and align new cuts with the original helix. Its split-die construction and indexing pins let you begin re-cutting on sound threads behind the damaged area so the repaired section feeds straight and true.

How does this split die prevent cross-threading during repairs?

Unlike single-piece dies that must engage damaged threads first, the split design lets you assemble the die around the fastener and position it so the cutting begins on undamaged threads. Dual indexing pins lock the two halves in the correct orientation to maintain tooth alignment, keeping the die square to the shank as you work.

• Split die construction enables repair starts behind the damaged zone
• Indexing pins align die teeth and secure halves during cutting
• Fits over the fastener so the first cuts follow existing thread pitch

What thread sizes and fasteners is this designed for?

This Steelman chaser is sized for M14-1.50 metric threads, a common specification for wheel studs, bolts, and other automotive fasteners. The 1-inch hex exterior accepts standard wrenches or 1-inch SAE sockets so you can use common hand tools for controlled, manual re-cutting.

• Exact thread profile: M14 x 1.50 metric
• External hex diameter: 1 inch — accepts 1" SAE sockets or wrenches
• Intended for bolts, studs, and metric fasteners found on cars and trucks

What materials and durability features does this tool have?

The die is manufactured from heat-treated SKD11 high-carbon, chromium-alloy steel for hardened edge life and consistent performance in repeated repairs. Steelman builds this tool to exceed ASME torque requirements, giving professionals and DIYers assurance that it will withstand the forces used while hand-driving dies.

• Made of hardened SKD11 high-carbon, chromium alloy steel
• Heat-treated for long-lasting cutting edges and wear resistance
• Meets or surpasses 150% of ASME torque standards for hand tooling

How should I use it safely for best results?

Always use this split die with hand-driven tools—sockets, wrenches, or adjustable wrenches—to avoid over-torquing or damaging the thread profile. Clean the fastener, clamp or stabilize the workpiece, and back off debris frequently; light cutting oil helps the chaser cut smoothly and prolongs tool life.

• Drive only by hand—no power tools—to protect threads
• Clean and degrease the fastener before starting
• Use cutting oil and remove metal shavings often

Who is this for: The Steelman M14-1.50 split die thread chaser is aimed at automotive technicians, fleet mechanics, and serious home mechanics who need a reliable, manual method to restore M14 metric threads on wheel studs and bolts. If you repair vehicles, maintain equipment, or want to avoid replacing studs and fasteners unnecessarily, this tool provides an efficient, long-lasting solution designed for professional shop use and informed DIYers.
