Not every Hinderer part is tied to a specific model. This page collects the universal hardware, the common pieces that fit across the Hinderer lineup, so you can restock or upgrade without matching a part to one particular knife.
Universal hardware covers the everyday items you go through or want spares of, like pivot and detent washers and the small screws that hold clips and filler tabs in place. Washers in particular are compatible across Hinderer knives, so a single kit keeps your whole rotation running smoothly whether you carry an XM, an Eklipse, or a Track. These are the parts that see wear from regular disassembly and reassembly, so having extras on hand keeps every knife tuned.
For anything that has to match a frame, such as pivots, standoffs, handle nuts, scale screws, lockbar stabilizers, and scales, you will want the set cut for your model rather than universal parts. You can find all of it, both universal and model specific, within the full range of Hinderer parts and accessories. When in doubt, confirm the fit before you order so the part drops in clean.
