Brass Fouling Scraper .58 Cal. Steel stud with 5/16 x 27 Hoppes Male Thread to use with our range rods. Stamped with an "8" for .58 caliber bores.
 
After brushing out the bore, this is a good tool to scrape lose the fouling buildup on the face of the breech plug and then pour it out of the barrel.
 
Our “K” cleaning jags and fouling scrapers with the 5/16 x 27 Hoppes male thread have thicker/heavier/wider shanks than button jags with 8 x 32 or 10 x 32 male thread shanks. With enough stress, anything can be broken. But the shanks on the 5/16 x 27 Hoppes male thread can tolerate more stress than smaller shanks.
