This report covers a study of the effectiveness of LOCTITE sealant as a locking method for the prevention of loosening of threaded fasteners under shock and vibration conditions. The weakest grade, LOCTITE H, was found to be as effective as the dab type materials MIL-V-173 varnish and MIL-B-11031 sealing compound under the test conditions used. However, LOCTITE sealant compounds should not be relied upon for fastening under high frequency, high amplitude vibration conditions. Application after fastener insertion is undesirable since extent of penetrability is unpredictable.
