DIN 931 specifies a hex head bolt with a plain shank beneath the head and thread over the lower portion only, making it suited to joints that carry shear across the joint line. Property class A4-70 indicates a minimum tensile strength of 700 MPa - stronger than standard A4-50 and suited to structural fixings where higher clamping force is needed. The unthreaded shank sits in the bearing hole rather than the thread, locating the joint accurately and presenting a solid cross-section to shear loads instead of the reduced root diameter of a thread.\u003c\/p\u003e\u003ch3\u003eTypical applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eStructural steel and heavy timber connections\u003c\/li\u003e\n\u003cli\u003ePivot points, brackets, and load-bearing joints\u003c\/li\u003e\n\u003cli\u003eMachinery frames and equipment mounting\u003c\/li\u003e\n\u003cli\u003eApplications where the joint carries shear rather than tension\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAvailable in packs of 10 to 50, with free next working day delivery on UK orders over £50 and 30-day returns.\u003c\/p\u003e","brand":"Simfix","offers":[{"title":"Pack of 10","offer_id":57505164362103,"sku":"931A41404570-D","price":21.68,"currency_code":"GBP","in_stock":true},{"title":"Pack of 50","offer_id":57505164394871,"sku":"931A41404570-T","price":98.23,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0991\/4728\/4855\/files\/simfix-23108050_1.png?v=1789550476","url":"https:\/\/simfix.com\/products\/m14-x-45-hexagon-head-bolt-din-931-a4-stainless-steel","provider":"Simfix","version":"1.0","type":"link"}
