Four Product Lines, One Engineering Standard
Thread strengthening and repair inserts for aluminum, titanium and soft-alloy assemblies.
Wire Thread Inserts
Helically coiled inserts that distribute load evenly and protect tapped threads in soft base materials.
Explore wire thread inserts →Tangless Inserts
No-tang design eliminates broken-tang FOD risk and speeds up installation and removal.
Explore tangless inserts →Self-Tapping Inserts
Cut their own thread in pre-drilled holes — well suited to titanium and hard-to-tap alloys.
Explore self-tapping inserts →Key-Locking Inserts
Solid-bodied inserts with locking keys for heavy-duty, high-vibration and high-temperature joints.
Explore key-locking inserts →Built for Demanding Industries
Application-proven fastening across four high-reliability sectors.
Aerospace
Airframe structures, landing gear attachments, FOD-sensitive assemblies.
Aerospace solutions →Gas Turbines
Hot-section housings fastened at 600°C+ with creep-resistant materials.
Gas turbine solutions →Semiconductor Equipment
Non-magnetic, low-outgassing inserts for vacuum chambers.
Semiconductor solutions →Field-Proven Case Studies
Five engineering cases from aerospace, gas turbine, semiconductor and data center programs.
Tangless Inserts in Aluminum Wing & Door Joints
Thread loading up 3–4×, assembly 35% faster, 10,000+ vibration cycles without loosening — zero broken-tang FOD risk.
Inconel X-750 Inserts at 600°C+
Silver-plated wire thread inserts hold bolt preload through thermal cycling and stop thread galling; full heat-number traceability.
Nitronic 60 & Phosphor Bronze in Vacuum Chambers
Non-magnetic, low particle generation and no thread cold-welding — meeting ultra-clean manufacturing requirements.
Key-Locking Inserts in Server Chassis
Zero back-out under vibration; 10× longer thread life across repeated maintenance cycles.
Self-Tapping Inserts in Titanium Brackets
Corrosion-protected coatings withstand salt-fog environments and impact loads without loosening.
Quality You Can Trace, Part by Part
Process discipline over certificate walls.
- First Article InspectionEvery new part number verified dimensionally before production release.
- 100% InspectionEvery insert checked before release — not sampling-based.
- Full Lot TraceabilityMaterial heat numbers and batch records retained for every shipment.
- AS9100D-Compliant ControlsProcess controls aligned with AS9100D-compliant quality management resources.
