The length listed (e.g., 4mm for M1×4mm) refers to the full shank length excluding the head. As a general rule, the screw should engage at least 1.5× its diameter of thread depth in the receiving material — for M1 screws, that means at least 1.5mm of thread engagement. For M1.2×1.4mm screws, the very short shank is designed for thin-panel or surface-mount applications.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-cta\"\u003e🛒 Select your \u003cstrong\u003esize and quantity\u003c\/strong\u003e above, then add to cart — ships from our US warehouse.\u003c\/div\u003e\n\u003c\/div\u003e","brand":"HomeDIYer","offers":[{"title":"M1X4mm \/ 50 Pcs","offer_id":52285213802770,"sku":"GLFBZBPJLWJ00016x50","price":9.42,"currency_code":"USD","in_stock":true},{"title":"M1.2X1.4mm \/ 50 Pcs","offer_id":52285213835538,"sku":"GLFBZBPJLWJ00017x50","price":9.42,"currency_code":"USD","in_stock":true},{"title":"M1X4mm \/ 100 Pcs","offer_id":52285213868306,"sku":"GLFBZBPJLWJ00016x100","price":13.5,"currency_code":"USD","in_stock":true},{"title":"M1.2X1.4mm \/ 100 Pcs","offer_id":52285213901074,"sku":"GLFBZBPJLWJ00017x100","price":13.5,"currency_code":"USD","in_stock":true},{"title":"M1X4mm \/ 150 Pcs","offer_id":52285213933842,"sku":"GLFBZBPJLWJ00016x150","price":15.26,"currency_code":"USD","in_stock":true},{"title":"M1.2X1.4mm \/ 150 Pcs","offer_id":52285213966610,"sku":"GLFBZBPJLWJ00017x150","price":15.26,"currency_code":"USD","in_stock":true},{"title":"M1X4mm \/ 200 Pcs","offer_id":52285213999378,"sku":"GLFBZBPJLWJ00016x200","price":19.72,"currency_code":"USD","in_stock":true},{"title":"M1.2X1.4mm \/ 200 Pcs","offer_id":52285214032146,"sku":"GLFBZBPJLWJ00017x200","price":19.72,"currency_code":"USD","in_stock":true},{"title":"M1X4mm \/ 300 Pcs","offer_id":52285214064914,"sku":"GLFBZBPJLWJ00016x300","price":28.67,"currency_code":"USD","in_stock":true},{"title":"M1.2X1.4mm \/ 300 Pcs","offer_id":52285214097682,"sku":"GLFBZBPJLWJ00017x300","price":28.67,"currency_code":"USD","in_stock":true},{"title":"M1X4mm \/ 400 Pcs","offer_id":52285214130450,"sku":"GLFBZBPJLWJ00016x400","price":37.59,"currency_code":"USD","in_stock":true},{"title":"M1.2X1.4mm \/ 400 Pcs","offer_id":52285214163218,"sku":"GLFBZBPJLWJ00017x400","price":37.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/8936\/1682\/files\/Main-01_b2c5d607-a61b-440e-8b1e-6b3eec949c6d.jpg?v=1780503127","url":"https:\/\/homediyer.com\/products\/m1-m1-2-stainless-steel-pentalobe-five-star-machine-screws","provider":"HomeDIYer","version":"1.0","type":"link"}
