M8 Stainless Steel Knurled Insert Nuts With Through Hole Heat Set Embedding For Injection Molding Beefed-Up 304 Stainless Steel Corrosion Resistant Fasteners For High Stress Plastic Parts
✔️ 304 stainless steel, knurled body, through-hole heat set
The M8 knurled insertion nuts are built from heavy-duty 304 stainless steel, delivering excellent corrosion resistance and long-lasting performance in high-stress plastic assemblies. They are ideal for heat-set embedding in injection-molded parts and automotive/electronics housings, providing a secure threaded connection without tapping.
✅ Heavy-Duty 304 stainless steel construction for corrosion resistance and long life✅ Straight knurling for secure anchoring, prevents rotation and pull-out
✅ Through-hole design compatible with heat insertion, ultrasonic welding, or overmolding
✅ Self-aligning tapered lead-in reduces installation errors and prep time
✅ Broad plastic compatibility: ABS, PC, nylon, PBT, and other engineering plastics
💡 What is a heat-set insert used for in plastic assemblies and how does knurling help? Heat-set inserts create durable threaded holes in plastic by embedding into the polymer, while knurling locks the insert against rotation and pull-out for reliable, vibration-resistant joints. - Durable threaded connections in plastics - Knurled surface increases grip and prevents loosening - Suitable for heat insertion, ultrasonic welding, or overmolding
