410Pcs Tiny Hex Socket Head Cap Screws Bolts, 304 Stainless Steel M2 x 4/6/8/10/12/16/20mm, Micro Allen Head Machine Screws, Nuts and Washers Kit with Hex Wrench, Fully Threaded Pitch: 0.4mm

With the tubes, the un-anodized threads always go into the head. Order some M2 x 4mm screws for the clip or use a Dremel and carefully trim the ones they give you. The ones they send are 5mm and are too long especially if using the rubber button. Tip put the nut on all the way before trimming so you can back it off when done and fix any thread weirdness from cutting or I have had good luck with these https://www.amazon.com/dp/B082XRX17Z?ref=cm_sw_r_ud_dp_76RP7TFSXRAZA3Z0W946&ref_=cm_sw_r_ud_dp_76RP7TFSXRAZA3Z0W946&social_share=cm_sw_r_ud_dp_76RP7TFSXRAZA3Z0W946&language=en-US Welcome to the club 😊!
