Thread Repair, Insert Installation & Precision Hole Preparation
Protect critical mechanical assemblies from stripped threads, galling, and vibration fatigue with aerospace-grade thread insert technology.
Precision Hole Preparation
Insert Installation & Helicoils
In-Situ Thread Reclamation
Accurate core drilling, precision counterboring, and specialized STI pitch tapping ensuring concentricity and surface finish in cast iron, aluminum, and high-tensile steel.
Professional installation of free-running wire inserts, screw-locking coils, and heavy-wall solid bushings calibrated to strict industrial engineering torque specifications.
On-site extraction of sheared studs, oversized re-threading, and permanent thread restoration for heavy mining machinery and factory production lines without complete disassembly.
Four Steps to Permanent Thread Integrity
Hole Audit & Sizing
Drilling & STI Tapping
Mandrel Driving & Break-off
Go/No-Go Gauge Testing
Inspection of parent material condition, wear assessment, and exact pitch depth verification before machining.
Clean core drilling and class-2B thread cutting using dedicated screw thread insert taps and cutting lubricants.
Comprehensive internal thread pitch verification and torque load validation to ensure unyielding mechanical retention.
Even insertion beneath the surface level followed by clean driving tang removal using tang break-off tools.
