MroMax 4Pcs M6 x 120mm Hex Head Screws Bolts, 304 Stainless Steel 18-8, Fully Threaded, External Hex Drive, for Mounting Chair, Handles, Rail, Pump, Wheels, Antenna Parts, Boat and Plastic Bumpers

Description

Product Overview

The MroMax 4‑piece M6 × 120 mm hex head screw set is engineered for durability and precision. Each bolt is forged from 304 stainless steel (A2‑70 grade), a material renowned for its superior corrosion resistance in harsh environments such as marine, chemical, and outdoor applications. The screws conform to ISO 4017 and DIN 944 standards, ensuring a consistent thread profile and a true 10 mm hex socket that fits standard Allen wrenches without cam‑out. With a fully threaded length of 120 mm and a 1 mm pitch, the fasteners provide a strong, uniform grip across a wide range of substrates, from metal frames to reinforced plastics. The polished finish not only enhances aesthetic appeal but also reduces friction during installation, allowing for faster assembly and lower torque requirements. Designed for versatility, the set includes four identical bolts, each packaged in a compact, moisture‑resistant pouch that protects the stainless surface from scratches and contaminants until use.

Usage

These hex head screws excel in a multitude of industrial and DIY scenarios. In marine settings, they secure railings, deck fittings, and antenna mounts where exposure to saltwater demands a fastener that will not rust or weaken over time. In manufacturing plants, they are ideal for assembling machine tool guards, pump housings, and wheel assemblies, offering a reliable connection that can withstand vibration and cyclic loading. Home improvement projects benefit from the screws’ ability to fasten chair legs, cabinet handles, and bathroom fixtures, providing a clean, flush finish that resists wear from frequent use. The 6 mm diameter and 120 mm length make them suitable for thick gauge materials, while the fully threaded design ensures that the load is distributed evenly along the shaft, reducing stress concentrations. Whether you are a professional mechanic, a boat builder, or a hobbyist tackling a custom furniture build, these bolts deliver the strength and corrosion protection needed for long‑term performance.

FAQ

What size options are available for the M6 hex head screws?

The M6 series includes a range of lengths from 30 mm up to 150 mm, all with a 6 mm diameter and 1 mm thread pitch. The 120 mm length is part of a broader catalog that also offers 40 mm, 65 mm, 80 mm, and other sizes to suit different thicknesses and load requirements.

Are these screws suitable for use on non‑metallic materials?

Yes. The fully threaded design and polished stainless steel surface allow the screws to be used on reinforced plastics, composite panels, and even hardwoods when paired with appropriate washers or inserts. The corrosion‑resistant coating prevents galvanic reactions with dissimilar materials.

How do I ensure proper torque when installing these bolts?

Because the hex socket is precisely machined to 10 mm, a standard 10 mm Allen wrench or socket will provide accurate torque application. We recommend using a torque wrench set to the manufacturer’s specification of 5–7 Nm for typical applications, adjusting as needed for higher‑strength substrates.

What warranty does MroMax provide for these fasteners?

MroMax offers a one‑year limited warranty covering material defects and manufacturing errors. If a bolt fails due to a defect, we will replace it at no cost. Our support team is available to assist with warranty claims and to provide technical advice throughout the product’s lifecycle.

Can I purchase additional quantities or different lengths in the same order?

Absolutely. Our inventory includes a full range of M6, M8, M10, M12, and larger diameters in various lengths. You can add any combination of sizes to your cart, and we will ship them together in a single, secure package.
