The tapered underside of the head seats into a matching countersunk hole, pulling the screw into alignment as it tightens and leaving nothing standing proud. That matters in places like skid plates, chassis rails, and body mounting hardware, where a raised head would drag on the ground, catch debris, or interfere with a part sitting above it.\u003c\/p\u003e\u003cp\u003eThe countersink also does something useful mechanically. Because the tapered head self-centres in its seat, a flat head screw locates the components it joins more precisely than a flat-bottomed head would, which helps keep alignment consistent through repeated disassembly.\u003c\/p\u003e\u003cp\u003eThe trade-off is that the head is thinner at the outer edge and the hex socket is shallower than on a cap head of equivalent size. That makes flat heads more prone to rounding out if a worn or incorrectly sized driver is used, so they are worth replacing rather than fighting once the drive starts to slip.\u003c\/p\u003e\u003cp\u003eThis is a direct factory replacement manufactured to the correct thread and countersink specification, installing in the stock locations with no modification.\u003c\/p\u003e","brand":"ARRMA","offers":[{"title":"Default Title","offer_id":55774087741762,"sku":"ARA722422","price":3.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5063\/8402\/files\/ARA722422_A0_CJ2SVBMR.jpg?v=1785969328","url":"https:\/\/www.powerhobby.com\/products\/arrma-ara722422-flat-head-screw-m4x22mm","provider":"PowerHobby","version":"1.0","type":"link"}
