M6 x 30mm Flanged Hex Head Bolts Mellewell Black Oxide – 20 pcs

Description

Product Overview

The M6 x 30mm flanged hex head bolt from Mellewell is engineered to meet the rigorous demands of modern industrial and scientific environments. Constructed from high‑grade alloy steel class 10.9, these bolts provide exceptional tensile strength while the black oxide coating adds a layer of corrosion resistance, extending the service life even in harsh, moisture‑laden conditions. The flanged design distributes load evenly across the fastening surface, reducing stress concentration and preventing material deformation. With a half‑threaded shank and a precise 1.0mm pitch, the bolt offers a secure, tight fit that resists loosening under vibration. Each package contains 20 meticulously inspected units, ensuring consistency and reliability for bulk projects, maintenance kits, and large‑scale assembly lines. The compact dimensions—30mm screw length excluding the head and a 28mm threaded portion—make these bolts ideal for applications where space is limited but strength cannot be compromised.

Usage

These flanged hex head bolts excel in a wide range of settings, from heavy‑duty machinery assembly to precision equipment repair. Their robust construction makes them suitable for mounting panels, securing brackets, and fastening structural components in manufacturing plants, automotive workshops, and aerospace facilities. The black oxide finish not only enhances aesthetic appeal but also protects against rust when used in outdoor installations, such as agricultural equipment, marine hardware, and outdoor lighting fixtures. Installation is straightforward: the hex head allows for easy torque application using standard wrenches or socket sets, while the flanged base provides a stable bearing surface that eliminates the need for additional washers in many cases. Whether you are a professional engineer, a maintenance technician, or a DIY enthusiast tackling a complex project, these bolts deliver the confidence of a secure, long‑lasting connection.

FAQ

What is the difference between a flanged hex bolt and a standard hex bolt?

A flanged hex bolt includes a built‑in washer‑like flange beneath the head, which spreads the load over a larger area, reducing stress on the material and often eliminating the need for a separate washer.

Can these bolts be used in outdoor or marine environments?

Yes. The black oxide finish offers enhanced corrosion resistance, making the bolts suitable for outdoor, marine, and other moisture‑exposed applications.

What torque specifications should be applied when installing these bolts?

For M6 bolts of this grade, a typical torque range is 7‑9 Nm. Always refer to the specific equipment manufacturer’s guidelines for exact torque values.

Are the bolts compatible with standard M6 nuts and washers?

Absolutely. The M6 thread size conforms to standard metric specifications, allowing seamless use with compatible nuts, washers, and other fastening accessories.

How does the half‑threaded design affect installation?

The half‑threaded shank provides a balance between quick installation and strong thread engagement, offering a secure hold while reducing the time needed to fully seat the bolt.

In summary, the M6 x 30mm flanged hex head bolts from Mellewell combine premium materials, thoughtful engineering, and user‑focused design to deliver a fastening solution that meets the high standards of industrial professionals worldwide. Whether you are assembling heavy machinery, performing routine maintenance, or building custom equipment, these bolts provide the reliability, strength, and convenience required for successful outcomes.
