The VALUE COLLECTION KP8158 is a pack of 50 hex jam nuts suited for general fastening applications across mechanical, plumbing, electrical, and structural assembly work. Hex jam nuts are thin-profile nuts used primarily as locknuts, threaded onto a bolt or stud and tightened against a standard nut or bearing surface to resist loosening under vibration or load. At a package weight of 0.01 pounds, these are lightweight fasteners intended for light-duty and medium-duty clamping tasks. Tradespeople and assembly technicians keep hex jam nuts on hand for maintenance, repair, and new construction work wherever a secondary locking nut is required.
Hex jam nuts see broad use across residential and commercial applications including HVAC equipment mounting, pipe support hardware, electrical panel and equipment assembly, and general mechanical fastening. They are a standard consumable in maintenance shops, service vans, and light manufacturing settings. The pack quantity of 50 units makes this SKU practical for bulk stocking on the bench or in a parts inventory.
Designed as a standard hex jam nut for general fastening applications. Verify thread size and pitch against your specific bolt or stud before installation.
Hex jam nuts are installed by a mechanic, maintenance technician, or licensed tradesperson using an open-end or combination wrench sized to the nut flats. Thread the jam nut onto the bolt or stud and snug it against the mating nut or surface, then hold the primary nut with one wrench while tightening the jam nut with a second wrench to create a locking effect. Always confirm thread size compatibility before installation to avoid cross-threading or fastener failure.
