How can I straighten out the springs? I can't use them coil uo as is.

Yes. They are manufactured to the DIN 315 standard, which controls thread dimensions for common metric fasteners from M4 through M12 (coarse pitch). Just match the size marked on your bolt.
Absolutely. 201 stainless steel offers good corrosion resistance for general outdoor use—think patio furniture, BBQ grills, gutter brackets, and garden planters. For constant saltwater exposure, 304 or 316 stainless would be an upgrade, but 201 performs reliably in typical home and shop environments.
No tools are required. The butterfly wings are designed for finger‑tightening, giving you enough leverage to secure components by hand. If you ever need a little extra snug, you can gently use pliers, but the nut is built for tool‑free convenience.
The assortment includes a practical range of the most‑used sizes (M4, M5, M6, M8, M10, and M12). The exact piece count may vary depending on the current kit configuration—please refer to the product images or the order‑specific listing for the latest quantity. Rest assured, you’ll receive a useful workshop mix.
Yes, they are built for repeated use. The stainless steel threads resist wear and galling, so you can tighten and loosen them many times without loss of performance—ideal for jigs, fixtures, and adjustable assemblies.
