Wera 05073599001 967 Spkl/9 Torx Bo Multicolor L-Key Set for Tamper-Proof Torx Screws, Blacklaser, 9 Pieces https://www.amazon.com/dp/B00E8HM9N2/ref=cm_sw_r_cp_tai_AmHSzb33HCBKB
and any version of these cheap portable sets
Chinese as hell but can get them for 3 bucks if you look and I got few of them ready as backups
some fixtures might not have the clearance for a screwdriver, and most clamping screw use 3/8 or 10mm
i personnaly love the round long wera sets, and i have bondhus sets for sacrificial purposes
great deals atm
