Hex Jam Nuts

Hexagon Jam Nuts


Description:

Hex jam nuts from ITA Fasteners are thin nuts which have the same dimensions as the standard hex nut for the head alone. Its primary application lies in fastening the standard nut into place by being threaded onto a bolt and made to run tight against the parent nut. This will ensure that the bolts do not move out of place and will be securely held against vibrations and small and constant movements. In another use, these nuts are used as a leveler to even out surfaces of operations.

It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear. Since these nuts are galvanised, they are incredibly durable can be easily used in high strength applications as long as the axial pressure on the body is low. They are also corrosion resistant. These nuts are mostly used to fasten soft materials which will break if a thicker fastener is used.
