Product Description

M4 x 6mm / M4 x 8mm | Grade 5 Titanium | For Motorcycle & Bicycle Applications

Add a distinctive performance look to your build with S-PARTS M4 Flower-Pattern Titanium Screws. Featuring a unique flower/star-pattern CNC-machined head, these screws combine lightweight Grade 5 Titanium (Ti-6Al-4V) construction with precision machining and high-end colored finishes.

Unlike conventional smooth button head screws, the distinctive patterned head is carefully CNC machined to create a refined, technical appearance that stands out on custom motorcycles, bicycles, and other performance-oriented builds.

Distinctive Flower / Star-Pattern Head

The signature feature of these screws is the CNC-machined flower/star-pattern head.

Rather than using a conventional smooth button head, S-PARTS machines a distinctive geometric pattern into the 9mm head, creating a more intricate and premium appearance.

This combination of flower-like geometry and mechanical detailing gives the fastener a recognizable custom look, making it especially suitable for visible hardware on motorcycles, bicycles, and performance builds.

Grade 5 Titanium — Lightweight & High Strength

S-PARTS uses high-quality Grade 5 Titanium (Ti-6Al-4V), the internationally recognized designation for the titanium alloy commonly known as TC4 in China.

With an average tensile strength exceeding 1050 MPa, the material combines high strength, low density, and excellent corrosion resistance.

Under comparable conditions, S-PARTS titanium fasteners offer mechanical performance comparable to 10.9-grade steel fasteners, while weighing approximately half as much as conventional steel hardware.

The result is an ultra-lightweight titanium fastener designed for riders and builders who want to reduce hardware weight without sacrificing the strength and durability expected from premium mechanical fasteners.

Precision CNC Machining

The screw body and decorative head are manufactured using precision CNC machining, with dimensional tolerances controlled to within ±0.02mm.

Every detail—from the threaded body to the 9mm patterned head—is carefully machined for consistent dimensions and a clean, precise finish.

This level of machining is more demanding and costly than conventional mass-produced steel hardware, but it allows S-PARTS to combine functional performance with distinctive visual detailing.

High-Performance Material Heritage

Titanium's combination of high strength-to-weight ratio, corrosion resistance, and low density has made titanium alloys a material of choice in demanding fields including aerospace and high-performance motorsport.

S-PARTS brings this high-performance material technology into the world of civilian customization, creating lightweight titanium hardware for motorcycles, bicycles, and other performance-oriented applications.

Aerospace-inspired material. Motorsport-inspired performance. Reinterpreted for everyday custom builds.

Advanced Surface Finishes

The colored versions use dedicated titanium surface-treatment processes rather than conventional paint.

Gold, Rainbow, Black, and Blue versions use PVD vacuum nitriding, creating vivid and durable surface colors while maintaining the metallic character of the titanium.

Green, Purple, Candy, and Indigo versions use anodized electrochemical oxidation, producing distinctive colors through controlled surface oxidation.

The result is a range of finishes designed to complement different motorcycle and bicycle builds—from understated Titanium and Black to more eye-catching Rainbow, Gold, Candy, and Indigo.

Ultra-Lightweight Performance Hardware

At just 0.63g per M4 x 6mm screw and 0.76g per M4 x 8mm screw, these fasteners offer an extremely low weight while retaining the strength and corrosion resistance advantages of Grade 5 titanium.

The 9mm flower/star-pattern head provides both a distinctive appearance and a broader head profile, while the T20 Torx drive provides a secure interface for installation.
