Each bolt measures 4 inches in length with a 3\/8-16 UNC thread, a flat head style, and a right-hand, partially threaded thread style rated Grade 2 hardness. The stainless steel construction resists corrosion in marine environments, making this kit a practical choice for securing a jack plate to a boat transom or for other compatible marine hardware applications that call for a 4 inch, 3\/8-16 UNC bolt. The bolts ship with an unfinished, silver exterior finish and a Thread Class of 1A. This kit includes 4 bolts as a complete set, so buyers replacing worn or corroded transom-to-jack-plate hardware can order one kit to cover a full mounting job. Because the kit is sold as a fastener set rather than a full mounting assembly, it is intended to pair with the nuts, washers, or plate hardware already in use on the boat. The 4-pack format and standardized 3\/8-16 UNC thread size make it straightforward to match against existing jack plate or transom hardware without needing to source bolts individually.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Bob's Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 110-100003\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e 4 Inch Transom to Jack Plate Bolt Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces:\u003c\/strong\u003e 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Length:\u003c\/strong\u003e 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 3\/8-16 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Style:\u003c\/strong\u003e Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Coverage:\u003c\/strong\u003e Partially Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Class:\u003c\/strong\u003e 1A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Style:\u003c\/strong\u003e Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Type:\u003c\/strong\u003e Bolt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade:\u003c\/strong\u003e Grade 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Unfinished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 6 x 4.5 x 1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.4 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the Bob's Machine 110-100003 bolt kit?\u003c\/strong\u003e The kit includes 4 stainless steel bolts, each 4 inches long with a 3\/8-16 UNC thread, sold together as a set under part number 110-100003.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size do these bolts use?\u003c\/strong\u003e Part number 110-100003 uses a 3\/8-16 UNC thread with a right-hand, partially threaded thread style and a Thread Class of 1A.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material are the bolts made from?\u003c\/strong\u003e The 110-100003 bolt kit is made from stainless steel, chosen for corrosion resistance in marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long are the bolts in this kit?\u003c\/strong\u003e Each bolt in the Bob's Machine 110-100003 kit measures 4 inches in length.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is this bolt kit designed to be used for?\u003c\/strong\u003e This 4-pack, sold as the 4 Inch Transom to Jack Plate Bolt Kit, is designed for securing a jack plate to a boat transom, and also suits other marine hardware that requires a 4 inch, 3\/8-16 UNC bolt.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre washers or nuts included with the 110-100003 kit?\u003c\/strong\u003e No, the Bob's Machine 110-100003 kit contains only the 4 bolts; it does not include separate nuts or washers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat grade are the bolts rated?\u003c\/strong\u003e The bolts in kit 110-100003 are rated Grade 2 hardness.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat head style do the bolts have?\u003c\/strong\u003e Bob's Machine part number 110-100003 uses a flat head style bolt.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat finish do the bolts come in?\u003c\/strong\u003e The 110-100003 bolts have an unfinished, silver exterior finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the bolt kit weigh?\u003c\/strong\u003e The Bob's Machine 110-100003 4-pack bolt kit weighs 1.4 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many bolts come in one kit?\u003c\/strong\u003e One Bob's Machine 110-100003 kit contains 4 bolts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the packaged dimensions of the kit?\u003c\/strong\u003e The 110-100003 bolt kit measures 6 x 4.5 x 1 inches as packaged.\u003c\/p\u003e","brand":"Bob's Machine Shop","offers":[{"title":"Default Title","offer_id":49027465609435,"sku":"BOB-110-100003","price":21.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/81jlzVqUXwL.jpg?v=1785331065","url":"https:\/\/www.goodvibesmarina.com\/products\/bobs-machine-4-inch-stainless-steel-bolt-kit-3-8-16-unc-4-pack-transom-to-jack-plate-mounting-bolts","provider":"Good Vibes Marina","version":"1.0","type":"link"}
