Helicoil 7/16-14 Insert Pack R1185-7

SKU CH-SPRA-F90XX

Contains 7/16-14 thread inserts for repairing damaged holes in automotive components

  • Chrome-molybdenum steel construction resists impact-tool stress
  • Engineered pressure transfer from thin to thick socket walls boosts strength
  • One-piece design eliminates weak joints under high torque
  • High-torque drive geometry reduces corner wear on fasteners and sockets
  • Tested to industrial specifications for reliable performance at competitive cost

Helicoil 7/16-14 Thread Insert Pack

This Helicoil pack contains inserts sized 7/16-14 for repairing damaged internal threads in metal components. Made from high-quality chrome-molybdenum steel, they restore original fastener strength in automotive and industrial assemblies. Each insert is engineered to transfer load from the thinnest socket wall toward thicker sections for increased durability. The pack suits mechanics and technicians needing reliable thread restoration.

Suited for stripped thread repair in steel or alloy

Technicians fixing spark-plug ports, manifold bolts or similar 7/16-14 holes will find the correct pitch and diameter here. The one-piece design works with impact tools and limits corner wear on fasteners during high-torque installation. Shops needing metric sizes, finer pitches or larger diameters must source a different kit. Buyers without a 7/16-14 tap or installation tool cannot complete the repair with this pack alone.

7/16-14 UNC thread size

The single specification that decides fit is the 7/16-14 thread designation, matching a 7/16 inch nominal diameter with 14 threads per inch. Only holes tapped to this exact Unified National Coarse standard accept these inserts. Verifying the damaged hole matches this pitch and diameter before purchase avoids mismatched repairs. The R1185-7 part number confirms the specific insert configuration supplied.

Questions about this item

Will the 7/16-14 thread size match the existing lug studs on my vehicle?

The inserts use a 7/16-14 thread pitch; verify your vehicle's stud specification before installation to ensure compatibility.

How can I confirm the chrome-molybdenum inserts are seating correctly after installation?

Properly installed inserts sit flush with the wheel surface and accept the lug nut through the full thread depth without cross-threading or binding.

Does the R1185-7 pack include the installation tool or must I purchase it separately?

The pack supplies the inserts only; a matching Helicoil installation tool for the 7/16-14 size is required and sold separately.
