Thread Chasers

Thread Chasers — New & Used

Thread chasers restore worn or damaged threads on nuts, bolts, castings, and machined parts—saving scrap and reducing downtime. Preferred in maintenance, fabrication, and machine-tool environments, they re-cut threads cleanly without removing material or stretching fasteners.

At Surplus Select, we carry a selection of new and used OEM thread chasers including sets and individual units from trustworthy brands. Our inventory updates daily, offering surplus-pricing opportunities for machine shops, fabrication shops, and maintenance teams looking to salvage hardware and extend component life.

Price Match — We match any authorized distributor on identical in-stock parts, so you can source parts at surplus pricing with distributor-level assurance.

Trade-In Credit — Have quality new surplus items? Trade them in for store credit toward the parts you actually need.

Fast U.S. Shipping — Most orders ship same or next business day from our U.S. warehouse to keep your line running.

Find Your Thread Chaser Fast (Search-First)

Search your part number (e.g., Rethreading Chaser Set M20 × 2.5, ACME internal chaser 1-1/2").
No PN? Try specs: “metric thread chaser”, “internal pipe thread chaser”, or “straight-flute thread chaser”.
Need a specific finish or configuration? Add details like “HSS coated”, “taper pipe”, or “dieset with factory case” to your search.
