Common metric fine pitches: M6×1.0mm, M8×1.0mm or 1.25mm, M10×1.0mm, 1.25mm, or 1.5mm, M12×1.25mm or 1.5mm. Check the specific variant for the exact pitch before ordering.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eQ: Why use fine thread instead of coarse thread?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eA: Fine thread provides greater clamping force per unit torque (due to smaller helix angle), better resistance to vibration loosening, and finer adjustment increments. It is preferred in automotive, hydraulic, and precision mechanical applications. Coarse thread is easier to assemble quickly and more tolerant of contamination.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eQ: Can I use a fine thread nut on a coarse thread bolt?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eA: No. Fine thread and coarse thread nuts are not interchangeable. Always verify the thread pitch of your bolt before selecting a nut. Mixing thread pitches will damage both the nut and bolt.\u003c\/dd\u003e\n\u003c\/dl\u003e","brand":"Keszoox","offers":[{"title":"2pcs M6 pitch 0.75","offer_id":46895271051499,"sku":"5:200099163#10pcs M6 pitch 0.75","price":4.9,"currency_code":"USD","in_stock":true},{"title":"5pcs M8 pitch 1.0","offer_id":46895271182571,"sku":"5:200099271#10pcs M8 pitch 1.0","price":7.14,"currency_code":"USD","in_stock":true},{"title":"2pcs M10 pitch 1.0","offer_id":46895271149803,"sku":"5:200148165#5pcs M10 pitch 1.0","price":5.68,"currency_code":"USD","in_stock":true},{"title":"2pcs M10 pitch 1.25","offer_id":46895271117035,"sku":"5:200148634#5pcs M10 pitch 1.25","price":5.84,"currency_code":"USD","in_stock":true},{"title":"5pcs M12 pitch 1.25","offer_id":46895271084267,"sku":"5:200169412#5pcs M12 pitch 1.25","price":8.3,"currency_code":"USD","in_stock":true},{"title":"2pcs M12 pitch 1.5","offer_id":46895271215339,"sku":"5:200172955#5pcs M12 pitch 1.5","price":8.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/1005\/8731\/files\/Stainless_Steel_Fine_Thread_Hex_Flange_Nut_M6_DIN6923.webp?v=1758696891","url":"https:\/\/keszoox.com\/products\/stainless-steel-fine-thread-hex-flange-lock-nut-din6923-m6-m12-304-a2-serrated","provider":"Keszoox","version":"1.0","type":"link"}
