For the length, add up the thickness of all the parts being clamped, then allow enough extra thread for the nut to engage fully. A 12mm screw is a short length, so it suits thin parts. If the screw is too short to show a full thread beyond the nut, choose a longer size.\u003c\/p\u003e\u003ch3\u003eHow to use\u003c\/h3\u003e\u003col\u003e\n\u003cli\u003eLine up the holes in the parts you are joining; they need to be large enough for an M4 thread.\u003c\/li\u003e\n\u003cli\u003ePass the machine screw through from the side you want the head to show.\u003c\/li\u003e\n\u003cli\u003eThread the nut on by hand to avoid cross-threading.\u003c\/li\u003e\n\u003cli\u003eTighten with a screwdriver while holding the nut with a spanner or pliers.\u003c\/li\u003e\n\u003cli\u003eDo not overtighten on thin or soft materials, as this can distort the parts or strip the thread.\u003c\/li\u003e\n\u003c\/ol\u003e\u003ch3\u003eFAQs\u003c\/h3\u003e\u003ch4\u003eWhat size are these M4 nuts and bolts?\u003c\/h4\u003e\u003cp\u003eThey are M4 x 12mm machine screws with nuts.\u003c\/p\u003e\u003ch4\u003eHow many come in a pack?\u003c\/h4\u003e\u003cp\u003eThere are ten screws, each with a nut.\u003c\/p\u003e\u003ch4\u003eWhat finish do they have?\u003c\/h4\u003e\u003cp\u003eThey are zinc plated, shown as ZP in the product name.\u003c\/p\u003e","brand":"Securpak","offers":[{"title":"Default Title","offer_id":67824391323921,"sku":"DS-2854600","price":1.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/7323\/0097\/files\/securpak-machine-screw-and-nut-zp-m4-x-12-pack-of-10-1.jpg?v=1792514055","url":"https:\/\/diysmith.co.uk\/products\/securpak-machine-screw-and-nut-zp-m4-x-12-pack-of-10","provider":"DIYSmith","version":"1.0","type":"link"}
