Product Description

DIN 931 Partially Threaded Hexagon Head Bolts — Overview

DIN 931 is the German standard for hexagon head bolts featuring a partially threaded shank (half thread). The unthreaded shank shares the same diameter as the nominal thread size, delivering excellent shear strength and superior joint rigidity compared with fully threaded DIN 933 bolts. These high-reliability OEM/ODM customizable fasteners are engineered for demanding industrial and manufacturing applications.

Key Features of DIN 931 Hex Bolts

Unthreaded solid shank improves shear resistance and prevents thread stripping under transverse loads
Precision rolled thread ensures smooth nut engagement and tight dimensional tolerance
Heat-treated high strength grades (8.8 / 10.9 / 12.9) suited for heavy-load applications
Full batch inspection with Mill Test Report (MTR) available upon request
Compatible with standard DIN 934 hex nuts and washers
