The Heli-Coil 1185-6CN750 Bulk Insert provides a professional-grade solution for the reliable restoration and reinforcement of 3/8-16 UNC threads across demanding automotive and industrial applications. This precision-formed helical wire insert ensures enhanced thread integrity, making it an essential component for high-volume maintenance, repair, and manufacturing operations where lasting durability is critical.

Key Features

• Precision Thread Restoration: Specifically engineered for 3/8-16 UNC fasteners, this 0.750" long insert facilitates accurate and secure thread repair, vital for critical engine, driveline, and machinery components.
• Enhanced Thread Strength: Constructed from cold-formed stainless steel, these inserts create internal threads that consistently surpass the original tapped hole's pull-out strength, delivering a robust and dependable repair.
• Optimized for Soft Alloys: Ideal for use in aluminum, magnesium, and other softer materials, effectively preventing common issues such as thread stripping, galling, and pull-out, especially under high clamp loads.
• Superior Corrosion Resistance: The inherent corrosion resistance of stainless steel extends the lifespan of repairs, even in harsh environments like under-hood and under-vehicle exposure, ensuring consistent torque retention.
• Bulk Packaging Efficiency: Offered in bulk, these inserts streamline workflows in production lines, large-scale repair facilities, and OEM applications requiring frequent and reliable 3/8-16 thread solutions.

Applications

This bulk insert is widely used for restoring or reinforcing 3/8-16 threads in crucial components such as aluminum engine blocks, cylinder heads, transmission housings, and various accessory brackets. Its versatility makes it indispensable across a broad range of vehicles, including domestic and import models, light to medium-duty trucks, and heavy industrial machinery. It is an invaluable resource for fleet maintenance, marine applications, and general manufacturing where compromised 3/8-16 threads in soft materials demand a permanent, high-strength repair.
