## Description

## What to know

M6x20 titanium bolts bring a lightweight design to hardware upgrades where fastener material and appearance matter. Their burnt blue PVD coating adds a distinctive finish and is designed for humid or salty environments, making them a practical choice for builds exposed to rain, road spray, or coastal air.

The umbrella-head design suits assemblies made for this head style. Compared with choosing fasteners by size alone, this set also offers titanium construction, a colored PVD finish, and a fully threaded form to consider when matching replacement hardware.

## Size & fit

Each bolt is M6x20, with a 6 mm diameter and metric, left-hand thread. The fasteners are fully threaded, and the umbrella head is intended for umbrella-head hardware. Match the size, thread direction, and head style to the assembly before installation, these details determine whether the bolt is appropriate for a particular mounting point.

The four-piece set can be useful when replacing several bolts in one assembly or keeping matching fasteners together for a project. For bicycle or motorcycle work, identify the specific fastener being replaced and use the same required thread and head configuration. The product is a focused alternative to a mixed fastener assortment when you need M6x20 titanium bolts in a consistent burnt blue finish.

## Practical tips

Keep the bolts with the hardware selected for the same assembly so the matching size and head style are easy to identify during a repair. When installing, align the left-hand thread correctly and start the bolt carefully by hand, this helps the threads engage as intended. Use an installation method appropriate for the surrounding component and its fastener requirements.

The titanium construction keeps the design lightweight, while the PVD coating is intended to resist corrosion in damp and salty conditions. That combination can suit weight-conscious bike builds, outdoor equipment, or other assemblies where a colored finish and exposure-conscious fastener choice are useful. The burnt blue color also makes the hardware visually distinct from plain-finish bolts when coordinating a custom build.

## Practical questions

**What thread and size does each bolt use?** Each one is M6x20, with a 6 mm diameter, metric left-hand thread, and a fully threaded body. Check that the receiving hardware calls for these specifications and an umbrella head.

**What are the bolts made of, and what is the finish?** They are titanium bolts with a burnt blue PVD-coated finish. The finish is intended for use in humid or salty environments, alongside the lightweight design of the titanium construction.

**How many bolts are in the set?** The set contains four bolts, useful for replacing a group of matching fasteners or keeping a coordinated set for a project.

## Buying verdict

Choose this TIRYTU set when your assembly calls for M6x20 left-hand-thread bolts with umbrella heads and you want titanium construction in a burnt blue PVD finish. It brings together a defined fit, a four-piece quantity, and a finish designed for humid or salty surroundings—well suited to targeted hardware replacements and weight-conscious builds.
