Schecter C-1 Hellraiser uses a pointed 6-in-line headstock, not 3+3, so the standard-line Grover 406 (3+3) does not fit. This 6-in-line Mini Locking Rotomatic matches the guitar's actual 10mm tuner holes.
Built with exactly this kind of tight headstock in mind, and the post size likely matches. Not independently confirmed on a real unit yet, worth checking before buying.
This mod is specifically built for tighter headstocks like Explorer, per its own product description, and 10mm post diameter likely matches. Not independently measured against a real Explorer unit, so this stays at Needs verification rather than Likely drop-in despite the strong fit on paper.

This is a 6-in-line tuner set. The Flying V headstock has three tuners on each side, so a 6-in-line set is the wrong layout for this guitar.
This SKU is the 6-in-line configuration, with post heights and handedness arranged for a single-sided headstock. The Flying V uses a 3+3 headstock, so a 3+3 set is required.
If you have fitted any of these to this Grover Mini Rotomatic Locking Tuners, 6-in-line, tell us what you found and we'll update the data.
