wrench has a .187" slot in a .34" shaft, to fit .36 or .44 large frame Navy or Army Colt Model revolvers. These generally use of our #PCC-S
stainless steel nipples with 12-28 threads (coarser pitch),, but some use six (6) of our #PIR-S
stainless steel nipples with M6-.75mm threads (fine pitch)..
Revolvers are made in batches, in Italy, to the importer's specifications. Nipple size can vary within a brand, from lot to lot. Generally, the 1858 Remington copies use the metric nipple. Generally, the Colt replicas made after 1980 use the 12-28 nipple. But we have seen variations.
Lubricate your percussion nipple threads with #BC-CTL
Choke Tube Lube, and easily remove them, even after hundreds of shots. It withstands high temperatures, and prevents thread galling.
Don't use too much torque on revolver nipples. Brute force can bend or break the thin wrench fingers. Not warranted against breakage, this is the strongest hardest best tempered wrench made, but you can break it if you try to remove stuck nipples. Made in the U.S.A.
Stuck nipple? Try soaking the cylinder in penetrating oil for a few weeks, and be gentle using this wrench. Once removed, use our #BC-CTL
Choke Tube Lubricant to prevent the nipple from ever becoming stuck.
Color of product will vary due to the heat treating process.
