Our finest, small cleaning brushes. Stainless steel stitching laced all the way through the handle keeps the bristles in place and prevents pull-out under even the heaviest use. Made for the aircraft industry to exceed mil specs so you know they'll last in the gun shop too. Handle is 7-ply, no split laminate that stands up to all solvents and hard scrubbing. Stainless steel crimped wire that holds its shape well. Fantastic for parts washing and also an excellent choice for removing welding scale in tight corners (like bolt knob jobs!). SPECS: .005" (.127mm) diameter bristles 3 rows of 7/16" (11.1mm) long bristles set 3/8" (9.6mm) wide Mfg: Brownells
