This particular version is no longer stocked. Please see our 5/64" Balldriver instead. (Description below is left here for reference.) 5/64" Ball-point Hex Wrench. Interactive LED Panels and kits ship with 3/4" aluminum standoffs and stainless screws. You can use this wrench (An "Allen" wrench-- a little wisp of hexagonal steel wire) to tighten the screws if you like. It's hardened steel with a tough but clean gold-plated finish. You probably don't need one of these-- you can actually tighten the standoffs by hand without it.
