2- MATERIAL - Button head cap screws are made from Alloy steel with a zinc-nickel coating, which provides enhanced corrosion resistance (over 400 hours neutral salt spray test) compared to standard black oxide finishes. This ensures reliable performance and appearance under harsh conditions like humidity, salt, or high temperatures, reducing maintenance and replacement costs.
3- Work Environment - zinc-nickel coated button head socket cap screws are ideally suited for demanding environments where superior corrosion resistance is critical. They excel in high-humidity outdoor applications, salt-laden coastal or de-icing settings, and high-temperature areas near machinery or engine compartments. This makes them a reliable and durable fastening solution for industries ranging from marine and automotive to construction and beyond.
4- Applications -Button Head Socket Cap Screws feature a low-profile, rounded dome head that provides a sleek and safe finish. Unlike flat heads, they sit above the surface without needing a countersunk hole, and offer a lower, smoother profile than socket head cap screws, making them for applications in fitness equipment, bicycles.
