The product (art. no. WS 9340) is used where countersunk, demountable fastening with a through-bolt is required. The design with an oval countersunk head provides a flush and integrated mounting surface, while the cylindrical sleeve part enables stable metric internal thread fastening in wood, composite, and panel materials. It is suitable for professional installations where dimensional accuracy and consistent function are critical.\u003c\/p\u003e\n\u003ch2\u003eAREA OF APPLICATION\u003c\/h2\u003e\n\u003cp\u003eThe product is used in the furniture industry, interior installation, construction, and technical installations. It is intended for applications where countersunk mounting from one side is combined with a metric internal thread for a through-bolt. The A2 material selection provides corrosion resistance in normal outdoor environments as well as good resistance to moisture and atmospheric exposure. The product is not intended for marine environments or environments containing chlorides.\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL SPECIFICATIONS\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eProduct type:\u003c\/strong\u003e Nut\u003cbr\u003e\u003cstrong\u003eProduct family:\u003c\/strong\u003e Slotted nut, oval countersunk head\u003cbr\u003e\u003cstrong\u003eMaterial class:\u003c\/strong\u003e A2\u003cbr\u003e\u003cstrong\u003eStrength class:\u003c\/strong\u003e Not specified\u003cbr\u003e\u003cstrong\u003eStandard:\u003c\/strong\u003e Non-standardized (art. no.

It is mounted through a pre-drilled hole in the workpiece, where it meets a through-going machine screw from the opposite side. The result is a very strong and reusable joint that clamps the material together without protruding nut edges.\u003c\/p\u003e\n\u003ch3\u003eWhat is the advantage of an oval countersunk head for panel and wood fastening?\u003c\/h3\u003e\n\u003cp\u003eThe oval countersunk geometry provides both functional and aesthetic benefits:\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eFlush and safe surface:\u003c\/b\u003e The countersink allows the nut to sit flush with the material so that no sharp edges protrude where clothing, equipment, or hands could get caught.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eEven pressure distribution:\u003c\/b\u003e The collar\/flange distributes the clamping force over a larger area, which prevents the nut from being pulled through softer materials like wood, plastic, or composite.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eClean surface finish:\u003c\/b\u003e The oval head provides an elegant, professional, and clean finish for visible mountings.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch3\u003eWhy is stainless steel A2 (AISI 304) suitable for slotted nuts and when should it be used?\u003c\/h3\u003e\n\u003cp\u003eStainless steel A2 (1.4301 \/ AISI 304) provides excellent corrosion protection in indoor environments, damp areas, and normal outdoor environments without direct contact with salt water or acids.
