The secret is in the Wedge-Locking Washer's super-hardened external teeth that \"bite\" into the bottom of the bolt head and the top flange surface. Vibrations that normally cause other bolts to loosen, are blocked by the wedge-locking action that uses tension, instead of friction to stay snug. In fact, contact with oil actually facilitates the effect. Installs\/uninstalls with a normal wrench, lubricate, and then reuse. Each set comes with twelve Hex Head, Grade 8 (12.9) steel bolts (3\/8\"-16 thread, 1\" long) with a black oxide finish, and pre-assembled Wedge-Locking Washers.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/summary\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFeature\/Benefit\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWedge-Locking Technology Eliminates Constantly Re-Tightening Exhaust Collector Bolts; Blocks Bolt-Loosening Rotation caused by Vehicle Vibrations.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHeader Bolts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHeader Bolts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFits GM V6, SB 265-400, Buick, Olds, Pontiac 79 and earlier, Mopar BB 383-440 exc 413, AMC V8's w 3\/8in bolts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003e\u003cstrong\u003ePackaging Information\u003c\/strong\u003e\u003c\/summary\u003e\u003cp\u003eWeight: 0.65 lbs\u003cbr\u003eDimensions: 6.75 x 4.5 x 1.75 IN\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003e\u003cstrong\u003eWarranty\u003c\/strong\u003e\u003c\/summary\u003e\u003cp\u003e1 Year Warranty\u003c\/p\u003e\u003c\/details\u003e\u003cdetails open\u003e\u003csummary\u003e\u003cstrong\u003e⚠ Fitment Notes\u003c\/strong\u003e\u003c\/summary\u003e\u003cul\u003e\n\u003cli\u003eHex Head;  3\/8 dia.
