✔️ 18 8 stainless steel, half inch twenty tpi, 250 piece bulk pack
These stainless steel helical inserts act as heavy duty threaded sleeves that fix stripped or worn out bolt holes in aluminum and softer metals. They come packed in bulk sets of two hundred fifty coils and stay put under heavy loads. Mechanics and fab shops drop them into engine blocks, brackets, and chassis components to get fasteners grabbing tight again without welding.

💡 What makes helical thread inserts handy for boosting load strength in weakened metal parts?
These coil style upgrades restore original factory threading while spreading force evenly across the base material.
- high tensile strength ratings keep bolts from spinning loose during heavy vibration cycles
- temperature resilient alloys maintain grip integrity when engines or machinery run hot
- seamless installation saves time compared to welding or oversize plugging methods
- reliable performance cuts down repeat service calls on rebuilt components
