Glvaner M10-1.5 x 35mm Alloy Steel Flanged Hex Bolt 10.9 Black Oxide

Description

Product Overview

The Glvaner M10-1.5 x 35mm hex bolt is engineered for high‑strength applications where reliability and durability are paramount. Constructed from 10.9 grade alloy steel, the bolt offers a tensile strength that exceeds many standard stainless steel fasteners, while the GB5789 compliant black oxide finish provides an additional layer of protection against moisture and mild chemicals. The full‑thread design ensures that the thread runs the entire length of the shank, delivering consistent grip and load distribution. A 15mm hex drive socket allows for rapid torque application using standard wrenches, reducing installation time on the shop floor.

The most distinctive feature is the extra‑large flanged washer head, measuring up to 22.3mm in diameter. This integrated washer eliminates the need for a separate component, simplifying inventory management and assembly processes. The head height of 9.2mm maximizes bearing surface area, which helps to spread clamping forces across a broader area, reducing the risk of material deformation or cracking under heavy loads.

Usage

Designed for a wide range of industrial and scientific applications, this hex bolt excels in environments such as machinery frames, heavy‑duty equipment, automotive chassis, and structural steel assemblies. The combination of a high‑grade alloy and corrosion‑resistant coating makes it suitable for outdoor installations, agricultural machinery, and facilities where exposure to humidity or light chemicals is common. Its full‑thread profile and large washer head are particularly advantageous in applications that require frequent disassembly and re‑torquing, as the washer head maintains consistent pressure without the need for additional locking devices.

Installation is straightforward: insert the bolt through the pre‑drilled hole, align the flanged washer against the mating surface, and tighten using a 15mm hex wrench or socket. For optimal performance, apply a torque within the recommended range for 10.9 grade bolts (typically 70‑90 Nm for this size) to achieve the intended clamping force without over‑stretching the threads.

Maintenance is minimal. The black oxide coating resists rust formation, but periodic inspection is advised in highly corrosive environments. If the coating shows signs of wear, a light re‑application of a compatible anti‑corrosion spray can extend the service life.

FAQ

What is the recommended torque for this M10‑1.5 x 35mm bolt?

For a 10.9 grade bolt of this size, a torque of 70‑90 Nm is typically advised. Always refer to your equipment’s specifications and use a calibrated torque wrench to avoid over‑tightening.

Can this bolt be used with a separate washer on the nut side?

Yes. While the flanged washer head provides load distribution on the bolt side, adding a standard washer under the nut can further enhance stability, especially in high‑vibration applications.

Is the black oxide finish suitable for marine environments?

The black oxide coating offers good protection against rust in dry or mildly humid conditions, but for full marine exposure we recommend an additional protective coating or using a stainless‑steel variant.

Do the dimensions include the washer head height?

Yes. The overall length of 35mm is measured from the bottom of the head (including the washer) to the tip of the shank, ensuring accurate fit in design calculations.

How many bolts are included in the package?

The listing specifies a pack of 10 pieces, each identical in size and finish, providing a convenient bulk quantity for larger projects.
