T Slot Bolts 12pcs M6 35mm Square Head Stainless Steel Roof Rack Kit

Description

Product Overview

The 12‑piece T‑slot bolt kit from Zhengmy is engineered for demanding roof‑rack applications where strength, durability, and corrosion resistance are essential. Each bolt is fabricated from premium 304 stainless steel, a material renowned for its ability to withstand harsh weather, road salt, and UV exposure without rusting or degrading. The bolts feature a robust M6 thread with a 35 mm (1.38 in) length, providing ample engagement depth for secure fastening while maintaining a low profile that minimizes aerodynamic drag. The square head, measuring approximately 20 × 20 mm, offers a large bearing surface that distributes load evenly across the rack, reducing the risk of deformation under heavy cargo. Accompanying each bolt are matching stainless‑steel nuts and flat washers, ensuring a complete, ready‑to‑install solution straight out of the box. The kit’s equal‑pitch thread design promotes consistent torque application, and the compact barrel shape of the bolts allows them to fit into standard T‑slot tracks found on most roof‑rack systems, bike carriers, ski racks, and cargo boxes. With a total package weight of just 8.78 oz, the kit is lightweight yet built to handle the rigors of long‑distance travel, making it an ideal choice for outdoor enthusiasts, adventure travelers, and commercial fleet operators alike.

Usage

Designed for versatility, these T‑slot bolts excel in a wide range of real‑world scenarios. Whether you are mounting a kayak carrier, securing a bike rack, installing a ski or snowboard holder, or reinforcing a cargo box, the stainless‑steel construction ensures a reliable connection that will not seize or corrode over time. The 35 mm length is optimal for most standard T‑slot tracks, allowing the bolt to sit flush while providing enough thread engagement to handle loads up to several hundred pounds. The square head’s generous surface area makes it easy to tighten with a standard hex key or socket wrench, reducing the chance of slippage during installation. For travelers who frequently switch between different roof‑rack accessories, the kit’s interchangeable nuts and washers simplify the process of swapping components, saving valuable time at the campsite or loading dock. Additionally, the bolts are suitable for use on aluminum or composite rack frames, as the stainless‑steel material is non‑galvanic and will not cause adverse reactions when in contact with other metals. This makes the kit a universal solution for both personal vehicles and professional service vans that require dependable, repeatable fastening across a variety of cargo configurations.

FAQ

What types of roof‑rack systems are compatible with these bolts?

These bolts are designed to fit any standard T‑slot track found on most aftermarket roof‑rack systems, including those used for kayak carriers, bike racks, ski boxes, and cargo carriers. The 35 mm length and M6 thread size are common dimensions that work with a wide variety of manufacturers.

Can I use these bolts on aluminum or composite rack frames?

Yes. The stainless‑steel material is non‑galvanic, meaning it will not cause corrosion when in contact with aluminum or composite materials. This makes the bolts safe for mixed‑material installations without risking electrochemical reactions.

How do I ensure proper torque when installing the bolts?

We recommend using a calibrated torque wrench set to the manufacturer’s specified range, typically between 8‑12 Nm for M6 stainless‑steel bolts. Applying consistent torque helps achieve a secure fit while avoiding over‑tightening that could damage the rack or the bolt head.

Are replacement parts available if a bolt is lost or damaged?

Yes. Zhengmy offers individual replacement bolts, nuts, and washers that match the specifications of this kit. You can contact our customer service team with the part number, and we will provide the exact component you need.

What is the warranty coverage for this product?

The kit comes with a one‑year limited warranty covering any manufacturing defects. If you encounter a problem related to material quality or workmanship, simply reach out to our support team for a replacement or refund according to the warranty terms.
