Please confirm the required thread type before ordering.
UNC and UNF threads are not interchangeable. UNC has a coarse thread pitch, while UNF has a finer thread pitch. Always match the bolt with the correct nut or threaded hole.
For better fastening performance, use matching 316 stainless steel nuts and washers when corrosion resistance is required.
These bolts are made from 316 stainless steel, also known as A4 stainless steel, which provides excellent corrosion resistance.
UNC means Unified National Coarse Thread. It has a coarse thread pitch and is commonly used for general fastening applications.
UNF means Unified National Fine Thread. It has a finer thread pitch and is often used where stronger thread engagement or vibration resistance is needed.
These are imperial size bolts, also called inch size bolts. They are different from metric bolts such as M6, M8, or M10.
Yes. 316 stainless steel is highly suitable for marine, coastal, humid, and outdoor environments because of its excellent corrosion resistance.
You need to use matching UNC or UNF nuts with the same diameter and thread pitch. Metric nuts or incorrect thread types will not fit.
Both fully threaded and partially threaded options can be supplied depending on size, length, and customer requirements.
Yes. Different diameters, lengths, thread types, and packaging options can be customized according to your requirements.
