Includes 120 brass heat-set inserts, 200 socket-head M3 screws, and 100 matching M3 nuts, plus a 60W digital soldering iron, 2 dedicated M3 insertion tips, 2 connecting rods, 2 hex keys, and a compartment storage case. Components stay separated by size for faster selection during assembly and maintenance\u003c\/li\u003e\n\u003cli\u003e10 Screw Lengths 3 Insert Sizes: Match hardware to different wall thicknesses, joint depths, and assembly needs. The kit includes M3 screws in 6, 8, 10, 12, 16, 18, 20, 25, 30, and 40 mm lengths, with 20 pieces of each size. It also includes three brass heat-set insert sizes—M3×4×5, M3×5×4, and M3×6×4—with 40 pieces of each size, giving you flexible options for prototypes, housings, brackets, and DIY builds\u003c\/li\u003e\n\u003cli\u003e60W Digital Temperature Control: Adjust the soldering iron from 200–500°C \/ 392–932°F and switch between °C and °F display modes. The clear digital screen helps you monitor temperature while working with different thermoplastics, insert sizes, wall thicknesses, and installation depths. Choose the heat setting based on the material’s temperature tolerance, and test on scrap material first before installing inserts in the finished part\u003c\/li\u003e\n\u003cli\u003eDedicated M3 Heat-Set Installation: Two M3 insertion tips and two connecting rods help transfer heat to the brass insert while supporting straighter placement. Select the matching insert, mount the M3 tip, heat the insert, hold the tool perpendicular to the printed part, and apply light downward pressure until the insert reaches the required depth. Remove the tool vertically and allow the plastic to cool before threading in the screw\u003c\/li\u003e\n\u003cli\u003eFor 3D-Printed Assemblies \u0026amp; Repairs: Add reusable M3 threaded connection points to compatible thermoplastic parts such as enclosures, brackets, jigs, fixtures, models, prototypes, and DIY components. The organized assortment makes it easier to replace hardware, revise designs, or service parts that are assembled repeatedly. Confirm pilot-hole diameter, insert depth, material temperature tolerance, and screw length before installation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOverview\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e M3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Brass、Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e DSHTP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem dimensions L x W x H:\u003c\/strong\u003e 3.94 x 1.57 x 1.18 inches\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DSHTP","offers":[{"title":"Default Title","offer_id":67602412536028,"sku":"B0GGH7DMKG-size-m3","price":41.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/0913\/3020\/files\/515WmqPxWJL.jpg?v=1790701460","url":"https:\/\/stemora.us\/products\/heat-set-insert-kit-for-3d-printing-threaded-insert-kit-for-plastic-420pcs-size-m3","provider":"Stemora","version":"1.0","type":"link"}
