Our hex head bolts are produced in strict accordance with international standards and supplied directly from factory for global B2B buyers.Our hex head bolts are made from high-strength materials, offering excellent corrosion resistance, wear resistance, and reliable mechanical performance. These bolts are widely used in industries such as construction, automotive, machinery, petrochemical, and power generation.
An Outer Hexagon Bolt, also known as a hex head bolt or external hex bolt, is a threaded fastener with a six-sided head designed to be tightened using a wrench or socket. It is one of the most widely used fasteners in structural and mechanical assemblies.
Our outer hexagon bolts comply with major international standards, including:
DIN 931 – Hexagon head bolt, partial thread
DIN 933 – Hexagon head bolt, full thread
ISO 4014 / ISO 4017
ASTM standards available upon request
Hexagonal Head Design: The hexagonal shape of the bolt head allows for easy installation and removal using hand tools or power tools, improving work efficiency.
High Strength and Corrosion Resistance: We use premium materials such as carbon steel, stainless steel, and alloy steel, and offer heat treatment options based on customer requirements, providing bolts with varying strength grades to suit different harsh environments.
Precision Threads: Manufactured with advanced processes, our hex head bolts feature precise threads that conform to international standards, ensuring perfect compatibility with nuts and internal threaded holes, providing a stable and secure connection.
