Carbon Steel Bolts

VRN Bolts are ideal for fastening liners in chutes, feeders, skips, buckets and many other high wear areas in mining, quarrying and related industries. The bolts are through-hardened up to 450 BHN hardness. An outstanding feature of the bolts is the raised head, which effectively plugs the bolt hole in the liner, thus preventing premature wear around the hole.
