Metric Hex Head Bolts

Metric Hex Head Bolts have a hex head and coarse or fine machine screw threads. Select from partially threaded or fully threaded. All short lengths are fully threaded; for partially threaded the minimum thread length is longer for larger bolt sizes. JIS B1180 and three sizes of ISO 4014 and ISO 4017 have heads that are smaller than their DIN counterparts. Steel, from Class 8.8 to 12.9, and stainless steel are available as are plain and zinc plated finishes. To differentiate between partial and full threads, we classify Hex Head Bolts as partially threaded and Hex Head Cap Screws as fully threaded. Hex Head Bolts are also called Machine Bolts.
