Schaller Strap Lock System S-Locks #14010301/Satin-Chrome ZEMAITIS The "S" in S-Locks stands for "save," "silent," and "S"challer's strap locks. The new and revolutionary S-Locks are remarkably quiet. The one-piece construction hardened steel strap buttons, decorative design, complete ease of handling, and the beautifully elegant locking wheel provide a very smooth action. 【Strap Buttons】 The new and unique one-piece construction strap buttons are self-tapping screws made of hardened steel. Attach to the guitar body using a 3mm hex wrench. ■ 4mm / 5/32" size self-tapping screws. Compatible with all strap buttons included with guitars. For Gibson guitars, you can replace them without adjusting the guitar's mounting holes or screws. ■ Made of hardened steel and twice the thickness of regular strap buttons, boasting the highest durability. ■ The included high-quality felt washers protect the guitar's finish from scratches caused by interference with the strap buttons. 【Strap Locks】 The new pull-up ball design allows for easy locking and release. ■ The thread length has been extended, allowing for secure attachment to straps over 6mm thick. ■ The slanted (angled) stainless steel locking bolt maintains permanent precision and reliability, and the finish will not wear. 【Locking Wheel】 The new locking wheel has a unique 3-step protection mechanism. ■ Turn the patented tool-free, automatically locking threaded locking wheel. ■ Tighten the locking wheel using a 2mm or 5/64" hex wrench or screwdriver. ■ Finally, secure with a set screw. You will never lose the wheel again.
