BROWNELLS - "In-Hole" Kit #2 ID-12

BROWNELLS “IN-HOLE" KITS

The Brownells “In-Hole” Kits provide a versatile assortment of precision coil springs designed for firearm repairs, custom builds, and general gunsmithing applications where springs must operate inside confined holes and recesses. Constructed from high-tensile spring wire and wound with controlled tension, these springs are engineered to compress smoothly while helping reduce binding for reliable operation.

Available in both light-duty and heavy-duty configurations, each kit includes a selection of spring sizes designed to function freely inside holes ranging from 3/32" (2.4mm) to 1/4" (6.4mm) diameter. These spring assortments are ideal for replacing worn springs, fabricating custom components, and maintaining a ready supply of commonly used spring sizes on the gunsmithing bench.
