Product Description

5/16" x 1-1/2" hex bolt (5/16-18 UNC) — a standard hex‑head fastener sized for a 1/2" wrench, offered in typical materials and finishes (zinc‑plated Grade 5 or Grade 8 steel, hot‑dip galvanized, stainless 18‑8/316, and silicon‑bronze). Nominal major diameter 0.3125" (5/16"), 18 threads per inch, and a 1.50" overall length make this a general-purpose bolt for machinery, structural assemblies and repair work; use with a matching 5/16-18 nut and SAE/USS washer. Available as full‑thread (tap bolt) or partially threaded hex cap screw; common dimensional standards include ASME B18.2.1 / SAE J429. See the linked product pages and spec tables for material, grade and finish options when specifying for corrosion resistance or required strength levels.
