Manufactured from A2 (SUS304) austenitic stainless steel with a passivated natural finish, these screws combine an aesthetically clean appearance with excellent corrosion resistance. The wide, low button head distributes clamping load over a larger surface area, making them ideal for soft materials, thin panels, and applications where a flush or decorative finish is required.\u003c\/p\u003e\n\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard:\u003c\/strong\u003e ISO

socket cap screw with a plain button head. ISO 7380-2 features a button head with a flange (wider bearing surface). This page covers ISO 7380-1 (no flange).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can button head screws handle the same torque as socket cap screws?\u003c\/strong\u003e\u003cbr\u003eNo. Due to the shallower socket depth in the button head, the maximum recommended tightening torque is lower than for standard socket cap screws (DIN 912). Button head screws are not recommended for high-torque structural joints.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Are A2 button head screws magnetic?\u003c\/strong\u003e\u003cbr\u003eA2 stainless steel is generally non-magnetic in the annealed state.
