Designed without adhesive backing, this hook fastener relies on mechanical engagement with its mating loop counterpart, the SJ3418FR, for a secure reclosable bond. It carries an engaged thickness of 0.15 inches and is rated for continuous use up to 250 degrees F. The SJ3419FR meets F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test requirements, making it suitable for aerospace, industrial, and protective-garment applications where flame resistance is a regulatory requirement. Licensed trade sewers, garment fabricators, and industrial maintenance personnel are the typical installers.\u003c\/p\u003e\u003cp\u003eThis fastener is used in applications where a clean, tailored appearance is required alongside reliable reclosable performance. Common uses include flame-resistant workwear, protective garments, aircraft interior panels, and industrial fabric assemblies subject to heat exposure. The no-adhesive design allows the fastener to be sewn directly onto fabric or textile substrates. The material is preshrunk for maximum dimensional stability and flatness, and the finished assembly is both washable and dry cleanable, supporting repeated laundering cycles in demanding service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFlame resistant construction meets F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test\u003c\/li\u003e\n\u003cli\u003eTemperature resistant to 250 degrees F for use in high-heat environments\u003c\/li\u003e\n\u003cli\u003eNo adhesive backing — sew-on attachment for permanent, stable bond to fabric\u003c\/li\u003e\n\u003cli\u003ePreshrunk nylon woven construction ensures dimensional stability and flatness after washing\u003c\/li\u003e\n\u003cli\u003eWashable and dry cleanable for use on garments and reusable fabric assemblies\u003c\/li\u003e\n\u003cli\u003eMates with 3M SJ3418FR loop fastener for a matched flame resistant reclosable system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to mate with the 3M SJ3418FR flame resistant loop fastener as part of a matched reclosable system for flame resistant garments and fabric assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis fastener is installed by sewing onto fabric or textile substrates using standard industrial sewing equipment — no heat activation or adhesive bonding is required. Confirm that thread and substrate materials meet the same flame resistance standards required by the application before installation. Follow applicable regulatory requirements, such as F.A.R. 25.853 for aerospace interiors, when specifying this fastener in regulated assemblies. Cut the roll to length using sharp shears to maintain a clean edge and prevent fraying.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nylon woven hook\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoll Length\u003c\/strong\u003e: 50 yards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngaged Thickness\u003c\/strong\u003e: 0.15 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature Rating\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlame Resistance Standard\u003c\/strong\u003e: F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdhesive\u003c\/strong\u003e: None\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00021200368776\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000051817\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344184082738,"sku":"7000051817","price":1192.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310517610.jpg?v=1782031041","url":"https:\/\/voomisupply.com\/products\/3m-7000051817-flame-resistant-hook-fastener-3-4-in-x-50-yd","provider":"Voomi Supply","version":"1.0","type":"link"}
