This 5 piece refill pack contains V-COIL free running type S inserts for BSW 3/4 x 10 thread repair. The key selection points are thread designation, insert length 1.0 D, insert execution, and the repair system already used in the component.
BSW identifies a Whitworth inch thread used on British standard fastening and repair tasks. Free running inserts are selected when normal screw running behavior is required after installation. Confirm the mating part, prepared hole, driving method, and cleanliness before you load the tool or insert. This makes the refill pack specific to production maintenance, workshop repair, field service, and plant engineering.
- repairing damaged internal BSW 3/4 x 10 threads with the V-COIL insert system
- refill stock for repairs requiring insert length 1.0 D
- free running screw assembly where no locking torque is required from the insert itself
- service work where the original screw size should remain usable after the repair
Note Use only with the correct STI tap, installation tool, and thread preparation process for BSW 3/4 x 10.
- insert length 1.0 D gives a clear selection reference for the required repair depth
- BSW 3/4 x 10 designation keeps the refill pack tied to one defined screw connection
- free running type S supports normal screw movement after correct installation
- refill pack format helps replenish inserts without duplicating tools already available in the workshop
Drawbacks
- This refill pack does not include preparation or installation tools; use a suitable V-COIL repair kit or tool set when the required tools are not already available.
- Compare BSW 3/4 x 10 and 1.0 D with the repair specification before opening the refill pack.
- Remove damaged thread material using the preparation tools specified for the repair system.
- Create the STI receiving thread with the matching repair tap.
- Clean the bore and thread flanks before the insert is installed.
- Install the wire insert to the specified seating position using the correct tool.
- Remove installation remnants where the process requires that action.
- Verify that the mating screw starts smoothly and reaches the required engagement.

- Where can you find V-COIL thread repair technical information?
