308 Hole-Type Inserts: High-Strength Vibration-Proof Threading for Aerospace to Electronics


The 308 hole-type insert is the ultimate thread reinforcement solution across extreme-performance industries. Featuring asymmetric locking threads and impact-resistant alloy construction, it delivers 40% higher fatigue life than ISO 14383 standards. From jet engine mounts to 5G antenna housings, its patented design eliminates thread stripping under dynamic loads.

Installation Protocol

☆ Material Prep:

Metals: Drill Ø = Insert Ø + 0.04mm (e.g., 6.04mm for M6)

Plastics: Drill Ø = Insert Ø - 0.1mm (interference fit)

☆ Drive:

300-500 RPM @ 2.5-4.0 N·m (pneumatic driver)

☆ Lock:

Final ¼ turn shears drive tang丨Activates sealing base


Technical Validation: 

22kN ultimate tensile strength (M8 size), survives 100G shock per MIL-STD-810H.
