Its function is to generate preload to keep the assembly stable against tension, shear, and vibration. Variants include through bolts, anchor bolts, and studs (threaded at both ends, without a head).\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary><h3>What is the difference between a bolt and a screw?<\/h3><\/summary>\n    <div>\n      <strong>Bolt<\/strong>: works with a nut; the thread is not formed in the substrate. Ideal when joining multiple parts or different materials.<br><br>\n      <strong>Screw<\/strong>: threads into a tapped hole in the component itself; does not use a nut.<br><br>\n      In design, the bolt prioritizes preload of the assembly and nut\u2013washer compatibility, while the screw depends on the strength of the substrate\u2019s thread.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary><h3>How does a manufacturer of special bolts approach production depending on series size and geometry?<\/h3><\/summary>\n    <div>\n      \u2022 <strong>Cold heading\/cold stamping + thread rolling<\/strong>: optimal for long series, high repeatability, and better fatigue resistance due to preserved fiber continuity.<br>\n      \u2022 <strong>Screw machining\/turning and auxiliary machining<\/strong>: ideal for custom bolts in short\/medium runs and complex geometries (special heads, grooves, holes, tapers, precise chamfers).<br>\n      \u2022 <strong>Heat treatments<\/strong> according to strength class, and anti-corrosion coatings (zinc plating, zinc-nickel, nickel plating) depending on environment and galvanic compatibility.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary><h3>Rolled vs. machined threads: when is each recommended and how does it affect bolt performance?<\/h3><\/summary>\n    <div>\n      <strong>Rolled threads (roll forming)<\/strong>: induce compressive stresses, preserve grain flow, and improve fatigue resistance and surface finish; the best option for long runs and standardized thread pitches, requires ductile material and tooling.<br><br>\n      <strong>Machined threads (turning\/milling\/tapping)<\/strong>: offer maximum flexibility for special geometries, difficult materials, or short\/medium runs; parameters must be carefully controlled to avoid micro-notches.<br><br>\n      In both cases, defining standard and tolerance (e.g., M \u2013 6g\/6H, UNC\/UNF), usable thread length, lead-in chamfer, and run-out control is key for proper assembly and tightening.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary><h3>How is service durability ensured in special bolts: corrosion, anti-loosening, and traceability?<\/h3><\/summary>\n    <div>\n      \u2022 <strong>Corrosion<\/strong>: select material (stainless steel A2\/A4) or coatings (zinc plating, zinc-nickel, zinc flake, nickel plating) depending on environment and galvanic compatibility. For bolts \u2265 10.9, consider hydrogen embrittlement mitigation (e.g., baking after galvanizing if applicable).<br><br>\n      \u2022 <strong>Anti-loosening<\/strong>: depending on vibration: self-locking nuts, serrated\/wave washers, anaerobic adhesives, torque\u2013angle tightening, or holes for pins\/wire-locking in custom bolts.<br><br>\n      \u2022 <strong>Traceability\/quality<\/strong>: class marking (8.8\/10.9\/12.9) and manufacturer, batch\/heat number, certificates (e.g., 3.1), coating thickness checks, torque\u2013tension testing (K factor), and, depending on sector, PPAP\/control plans.\n    <\/div>\n  <\/details>\n<\/section>\n\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Special bolts At Lemec, we manufacture special bolts for virtually any industrial application and in different geometries and alloys.
