W-Style Iron Snap Spring Buttons in 15mm Diameter

The MH 15mm W-style iron snap spring button is a press stud whose W-shaped spring grips the stud on closing, holding two fabric layers together without a sewn buttonhole. W-style refers to the spring geometry inside the socket, which spreads the holding force across four contact points and gives the button a firm, repeatable click.

The button is made from iron and finished by electroplating or painting, so the exposed face resists scuffing and stays true in color after garment washing. The 15mm diameter is the larger of the standard W-style sizes, which suits heavier cloth where a small stud would pull through. MH also produces the same spring mechanism in brass and stainless steel, and in smaller W-style diameters as well as an O-style socket.

Garment factories fit this snap spring button on jeans, jackets, down jackets, windbreakers, hats and shoes, and craft workshops use it for DIY closures. MH manufactures the component in China and works to buyer drawings on material, size, style and surface finish.

W-spring holding force: The MH W-style snap spring button spreads its grip across the spring's contact points, so the closure stays shut on heavy cloth and reopens without deforming.

Iron body with plated or painted face: Electroplating and painting protect the iron snap button against scuffing and keep the face color stable through garment washing.

Made for hard-wearing garments: The snap spring button suits jeans, jackets, down jackets, windbreakers, hats and shoes, where closures are opened and closed constantly.

OEM material and style options: MH produces the same spring mechanism in iron, brass and stainless steel, in both W-style and O-style sockets and several diameters.

Certified for apparel: The snap button is OEKO-TEX certified, supporting its use on garments sold into markets that require textile safety documentation.
