Abstract

619,407. Bolt hole linings. AIRCRAFT SCREW PRODUCTS CO., Inc. Dec. 7, 1946, No. 36244. Convention date, Jan. 3. [Class 89 (i)] A thin resilient sheet metal liner for female screw threads is made by helically corrugating a tube or by helically coiling a strip having a single V-shaped corrugation the sides of the corrugation being concave at 20 for resilient flattening between the nut and bolt members to secure a locking effect. The concavity may be internal instead of external and in the'case of strip the gap may be either at the crest or root of the threads.
