The product is used as a pivot pin in clevis joints where a detachable and movable attachment is required. The pin is inserted through components with matching holes and secured with a cotter pin through the cross-hole, which prevents axial displacement. It is suitable for installations where high corrosion resistance, precise fit, and reliable mechanical function are crucial.\u003c\/p\u003e\n\u003ch2\u003eAPPLICATION AREA\u003c\/h2\u003e\n\u003cp\u003eThe product is used in marine rigging, wire systems, fitting systems, and mechanical links. It is intended for applications where an articulated attachment is required, such as in fork fittings, turnbuckles, shackles, and other rigging components. The clevis pin allows for rotation in the joint while being secured with a cotter pin to prevent accidental loosening. The material choice provides resistance to saltwater, moisture, and chemically aggressive environments.\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL SPECIFICATIONS\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eProduct type:\u003c\/strong\u003e Bolt\u003cbr\u003e\u003cstrong\u003eProduct family:\u003c\/strong\u003e Clevis pin\u003cbr\u003e\u003cstrong\u003eMaterial class:\u003c\/strong\u003e A4\u003cbr\u003e\u003cstrong\u003eStrength class:\u003c\/strong\u003e Not specified\u003cbr\u003e\u003cstrong\u003eStandard:\u003c\/strong\u003e Not specified\u003cbr\u003e\u003cstrong\u003eDiameter:\u003c\/strong\u003e 4–20 mm\u003cbr\u003e\u003cstrong\u003eDesign:\u003c\/strong\u003e With cross-hole for cotter pin\u003cbr\u003e\u003cstrong\u003eSurface finish:\u003c\/strong\u003e Bright\u003cbr\u003e\u003cstrong\u003eEnvironment:\u003c\/strong\u003e Marine\u003cbr\u003e\u003cstrong\u003eDelivery unit:\u003c\/strong\u003e Piece\u003c\/p\u003e\n\u003ch2\u003eFREQUENTLY ASKED QUESTIONS (FAQ)\u003c\/h2\u003e\n\u003ch3\u003eWhat is a clevis pin and how does it differ from a standard bolt?\u003c\/h3\u003e\n\u003cp\u003eA clevis pin has a completely smooth cylindrical body without threads and a pre-drilled cross-hole at the lower end. It acts as a pivot pin in clevis joints and linkage systems, allowing mobility in the joint without wear occurring on thread flanks. Instead of a threaded nut, the clevis pin is secured quickly and securely with a cotter pin, R-clip, or split ring.\u003c\/p\u003e\n\u003ch3\u003eHow is the clevis pin correctly secured against axial displacement?\u003c\/h3\u003e\n\u003cp\u003eTo prevent the pin from sliding out of its position, a suitable locking pin (e.g., cotter pin or split ring in A4 stainless steel) is inserted through the cross-hole at the end of the pin.\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eFor permanent installations:\u003c\/b\u003e Use a cotter pin whose legs are bent outwards after installation.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eFor frequent dismantling:\u003c\/b\u003e An R-clip or split ring is advantageously used, which can be easily removed without tools.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch3\u003eWhy is acid-proof A4 \/ AISI 316 crucial for clevis pins in marine and industrial environments?\u003c\/h3\u003e\n\u003cp\u003eClevis pins are often subjected to high shear forces while being located in crevice-like spaces inside fork fittings and turnbuckles. Acid-proof A4 steel (AISI 316 \/ 1.4401) contains molybdenum, which provides maximum protection against crevice and pitting corrosion that can otherwise quickly occur in damp, salty, or chemically aggressive environments. This ensures that the pin retains its load-bearing capacity and does not seize during maintenance.\u003c\/p\u003e","brand":"WASI","offers":[{"title":"4 \/ 12","offer_id":50976667763030,"sku":"100011","price":8.75,"currency_code":"SEK","in_stock":true},{"title":"4 \/ 14","offer_id":50972181725526,"sku":"400220","price":8.6,"currency_code":"SEK","in_stock":true},{"title":"4 \/ 15","offer_id":50976675234134,"sku":"100012","price":9.0,"currency_code":"SEK","in_stock":true},{"title":"4 \/ 19","offer_id":50972181758294,"sku":"400221","price":9.2,"currency_code":"SEK","in_stock":true},{"title":"4 \/ 27","offer_id":50976702628182,"sku":"100013","price":10.0,"currency_code":"SEK","in_stock":true},{"title":"5 \/ 12","offer_id":50976626573654,"sku":"100001","price":9.0,"currency_code":"SEK","in_stock":true},{"title":"5 \/ 15","offer_id":50974894850390,"sku":"400222","price":9.2,"currency_code":"SEK","in_stock":true},{"title":"5 \/ 18","offer_id":50972181791062,"sku":"400223","price":10.3,"currency_code":"SEK","in_stock":true},{"title":"5 \/ 21","offer_id":50972181823830,"sku":"400224","price":11.5,"currency_code":"SEK","in_stock":true},{"title":"5 \/ 23","offer_id":50976652493142,"sku":"100005","price":11.9,"currency_code":"SEK","in_stock":true},{"title":"5 \/ 26","offer_id":50976719569238,"sku":"100018","price":12.0,"currency_code":"SEK","in_stock":true},{"title":"6 \/ 15","offer_id":50972181856598,"sku":"400225","price":11.9,"currency_code":"SEK","in_stock":true},{"title":"6 \/ 13","offer_id":50987101356374,"sku":"100006","price":11.0,"currency_code":"SEK","in_stock":true},{"title":"6 \/ 20","offer_id":50972181889366,"sku":"400226","price":12.3,"currency_code":"SEK","in_stock":true},{"title":"6 \/ 21","offer_id":50987376968022,"sku":"101071","price":12.45,"currency_code":"SEK","in_stock":false},{"title":"6 \/ 22","offer_id":50976658882902,"sku":"100008","price":12.5,"currency_code":"SEK","in_stock":true},{"title":"6 \/ 25","offer_id":50972181922134,"sku":"400227","price":13.0,"currency_code":"SEK","in_stock":true},{"title":"6 \/ 29","offer_id":50972181954902,"sku":"400228","price":14.5,"currency_code":"SEK","in_stock":true},{"title":"6 \/ 36","offer_id":50972181987670,"sku":"400229","price":15.0,"currency_code":"SEK","in_stock":true},{"title":"6 \/ 45","offer_id":50972182020438,"sku":"400230","price":16.0,"currency_code":"SEK","in_stock":true},{"title":"8 \/ 17","offer_id":50976704692566,"sku":"100014","price":16.2,"currency_code":"SEK","in_stock":true},{"title":"7 \/ 21","offer_id":50987310973270,"sku":"101073","price":16.2,"currency_code":"SEK","in_stock":true},{"title":"8 \/ 21","offer_id":50972182217046,"sku":"400231","price":16.8,"currency_code":"SEK","in_stock":true},{"title":"8 \/ 24","offer_id":50972182249814,"sku":"400232","price":18.15,"currency_code":"SEK","in_stock":true},{"title":"8 \/ 27","offer_id":50972182348118,"sku":"400233","price":17.9,"currency_code":"SEK","in_stock":true},{"title":"8 \/ 32","offer_id":50972182446422,"sku":"400234","price":20.3,"currency_code":"SEK","in_stock":true},{"title":"9.5 \/ 26","offer_id":50972182577494,"sku":"400235","price":16.0,"currency_code":"SEK","in_stock":true},{"title":"9.5 \/ 30","offer_id":50972182610262,"sku":"400236","price":16.8,"currency_code":"SEK","in_stock":true},{"title":"10 \/ 22","offer_id":50976716882262,"sku":"100015","price":24.0,"currency_code":"SEK","in_stock":true},{"title":"10 \/ 30","offer_id":50972182643030,"sku":"400237","price":25.0,"currency_code":"SEK","in_stock":true},{"title":"12 \/ 30","offer_id":50972182708566,"sku":"400238","price":32.0,"currency_code":"SEK","in_stock":true},{"title":"15 \/ 41","offer_id":50972182741334,"sku":"400239","price":49.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0776\/7864\/1494\/files\/riggbult-rostfritt-A4_d3fa759e-dff1-4a89-b47b-aa33365ae270.jpg?v=1785841161","url":"https:\/\/rostfri.nu\/en\/products\/riggbult-a4","provider":"Rostfri.nu","version":"1.0","type":"link"}
