M3 x 25mm Hex Socket Button Head Cap Screws with Hex Key

Designed for versatility and durability, the M3 x 25mm Hex Socket Button Head Cap Screws package includes a total of 100 high-performance screws, perfect for a variety of applications ranging from robotics projects to furniture assembly. Each screw features a thread size of 3 mm and a thread pitch of 0.5 mm, ensuring a secure fit in countless materials. The length of 25 mm with an overall total length, including the head, of 26.53 mm makes these screws suitable for thicker materials and structural components, setting it apart from many standard screw options available on the market.

The innovative button head design gives these screws a sleek profile while maintaining excellent clamping capability. With a head diameter of 5.50 mm and a head height of 1.53 mm, these screws present a low-profile appearance that is both aesthetically pleasing and functionally advantageous. The hex socket drive, also referred to as internal hex drive, allows for effective torquing using the included hex key, ensuring easy installation and removal with minimal stripping potential compared to traditional Phillips head screws. This design feature makes it an ideal choice for precision engineering and assembly where both strength and appearance are crucial.

Crafted from premium alloy steel 40Cr and finished with black oxide, these screws are not only robust but also resistant to corrosion and rust, enhancing their longevity and performance in various environments. With a strength grade of 12.9 and a hardness range of HRC 39-44, these screws can handle significant stress, with a tensile strength rating of 1220 N/mm². Such specifications elevate these screws above typical offerings, making them an excellent choice for demanding tasks, including automotive applications and industrial machinery. Comparatively, lower grade screws may struggle under similar conditions, underscoring the value of investing in higher quality hardware.

The package comes complete with a 2.0 mm hex key, made of chrome-vanadium steel with a nickel-plated finish to resist rust and improve longevity. The inclusion of this tool is a thoughtful touch that ensures users are equipped with everything needed for quick and efficient installation right out of the box. The hex key's higher strength contributes to a reliable tightening and loosening experience, further enhancing the usability of these screws in various projects. The organized plastic storage case conveniently keeps all 100 screws and the hex key in one location, making it easy to transport and access when needed.

In comparison to equivalent products on the market, the M3 x 25mm Hex Socket Button Head Cap Screws stand out due to their superior material composition and strength properties. Many other offerings in the same size range often lack the structural integrity and corrosion resistance that these screws provide. Users can feel confident that they are choosing a reliable option for both simple household repairs and more complex engineering tasks, offering a balance of aesthetics, performance, and reliability that is hard to find elsewhere.
