Questions about this product
- What lengths come in this 100-set assortment?
- You get 100 sets across lengths from 4mm up to 30mm. The mix includes 4, 5, 6, 8, 10, 12, 15, 18, 20, 25, and 30mm posts. Each set has a male and female part for two-piece binding.
- What are these binding screws good for?
- They give a clean, reversible fastener for bookbinding, leatherwork, and signage. The two-part design lets you take pages or panels apart later. People also use them for portfolios, ledgers, and layered acrylic.
- What are they made of and how is the finish?
- The screws are steel with a black plated finish. That coating resists corrosion and gives a tidy, professional look. The spec sheet notes a 96-hour salt spray test for corrosion resistance.
