To<br \/>\ndetermine the bolt pretension achieved by application of a known<br \/>\ntorque, the results of 1900 tests were analysed to yield curves for<br \/>\nboth lubricated and unlubricated threads of BSF(BA) and Unified or<br \/>\nISO metric forms. The test data related to nuts of mild and high<br \/>\nstrength steel seated on mild or high strength steel or aluminium<br \/>\nalloy washers, and lubricants ranged from light oil to extreme<br \/>\npressure greases. No significant trend with material or lubricant<br \/>\nwas found. Techniques for applying a known torque are considered,<br \/>\nand their accuracy reviewed. Methods of locking the nut are<br \/>\ndescribed, together with their advantages and disadvantages, and<br \/>\ninclude mechanical, frictional, adhesive or deformation<br \/>\ntechniques.\n\t<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Applying, Measuring and Maintaining Pretension in Steel Bolts<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/esdu\/\"><b>ESDU<\/b><\/a><\/td>\n<td>2012-03<\/td>\n<td>23<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":557516,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2675],"product_tag":[],"class_list":{"0":"post-557507","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-esdu","8":"first","9":"instock","10":"sold-individually","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/557507","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/557516"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=557507"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=557507"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=557507"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
