The Panelock is a highly customised two-piece bolt-&-nut type fastener. When installed, a high tensile, low profile splined bolt with an undercut head, nitrile seal and Scotch-grip patch on the thread matches neatly with a star-drive T-nut. Externally tamperproof, the assembly is optimal for metal/wood applications where a Low-Profile finish is desirable on both-sides. Door hardware and frame/bulkhead attachments to GRP are favored applications. Bolts are supplied with nitrile weather seal under the head.
