The SJ3442 features 170 mushroom-shaped stems per square inch. When two strips are pressed together, the interlocking stems generate tensile strength capable of replacing conventional mechanical fasteners. The engaged thickness measures 0.16 inches. The strip is black and ships without a pressure-sensitive adhesive backing, making it suited for applications where the fastener will be bonded, sewn, or otherwise attached by the installer. Trade professionals and assembly technicians use this format for clean, repeated open-and-close attachment points.\u003c\/p\u003e\u003cp\u003eThis fastener has a documented history of use across transportation, electronics, business equipment, industrial machinery, medical devices, and sign and display applications. The no-adhesive plain back provides flexibility in mounting method, allowing the strip to be die-cut, heat-welded, or mechanically fastened to a substrate. It is well suited to both light-gauge panel attachment and equipment access covers where tool-free reclosable fastening is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e170 stems per square inch for high-density interlocking engagement\u003c\/li\u003e\n\u003cli\u003eEngaged thickness of 0.16 inches when two mating strips are joined\u003c\/li\u003e\n\u003cli\u003ePlain back with no adhesive — compatible with a wide range of secondary attachment methods\u003c\/li\u003e\n\u003cli\u003eBlack color for low-visibility or color-matched installations\u003c\/li\u003e\n\u003cli\u003e1-inch wide strip on a continuous 50-yard roll for field cutting to length\u003c\/li\u003e\n\u003cli\u003eMushroom-stem geometry generates tensile strength sufficient to replace mechanical fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style reclosable fastener strip for use wherever a plain-backed, no-adhesive Dual Lock format is specified in transportation, electronics, industrial equipment, medical, or display assembly applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by fabricators, assembly technicians, or trade professionals depending on the end application. The plain back requires a secondary bonding or mechanical attachment step before the fastener is placed into service. Cut the strip to length using a sharp utility knife or shears; avoid crushing the stems during cutting. Ensure the mating substrate is clean and dry before applying any adhesive or heat-weld process to the back surface.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Density\u003c\/strong\u003e: 170 stems per square inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngaged Thickness\u003c\/strong\u003e: 0.16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 50 yards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: Plain, no adhesive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00021200862304\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: 7010339596\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347767001394,"sku":"7010339596","price":901.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310518258.jpg?v=1782113246","url":"https:\/\/voomisupply.com\/products\/3m-7010339596-dual-lock-reclosable-fastener-sj3442-black","provider":"Voomi Supply","version":"1.0","type":"link"}
