Full Thread Hex Bolt DIN 933 / ISO 4017 Carbon Steel & Alloy Steel Fastener for Construction and General Industry

Full Thread Hex Bolts, also known as fully threaded hex head bolts, are standard fastening components with a hexagonal head and thread running along the full nominal length of the shank. Manufactured to DIN 933 and ISO 4017 dimensional standards, they are designed for metal-to-metal clamping, steel component assembly, bracket fixing, equipment installation, and general-purpose bolting work.

This product range is available in carbon steel and alloy steel to support different project, strength, and operating requirements. The full-thread design gives installers greater adjustment flexibility when the required grip length varies or when the bolt is used with nuts, washers, slotted holes, brackets, and fabricated steel parts. It is a practical choice for construction supply, solar mounting systems, machinery assembly, and industrial maintenance procurement.

Key Features

Full-thread construction: The thread extends along the bolt shank, providing flexible positioning and engagement for nuts and connected parts.

DIN 933 / ISO 4017 standard: Suitable for projects and purchasing programs that require commonly recognized metric full-thread hex bolt specifications.

Carbon steel and alloy steel options: Material selection can be aligned with the required mechanical performance and project application.

Hex head drive: Allows efficient tightening with standard spanners and sockets on site or in assembly lines.

Suitable for bulk industrial supply: A widely used fastener type for construction, photovoltaic support structures, equipment installation, and general industry.

Compatible fastening system: Can be supplied for use with matching hex nuts, including DIN 934 hex nuts, and suitable washers according to the assembly requirement.

Typical Applications

Full Thread Hex Bolts are commonly used where a reliable removable fastening connection is needed. Typical applications include:

Steel structures, brackets, frames, and fabricated metal assemblies

Solar photovoltaic mounting rails, supports, and accessory connections

Machinery, equipment bases, guards, and maintenance assemblies

Construction installation and general site fastening work

Industrial racks, platforms, enclosures, and utility fixtures

OEM assembly and general-purpose hardware kits

Why Choose a Full Thread Hex Bolt

For assemblies with variable thicknesses, brackets, spacers, or multiple joined components, a full-thread bolt gives more usable threaded length than a partially threaded bolt. This makes it especially suitable for fastening systems where nut position must be adjusted during installation. The hex head offers a familiar and efficient installation method, while DIN 933 and ISO 4017 provide a clear basis for communicating metric product requirements with purchasing teams and project contractors.

When selecting the product, buyers can define the required diameter, length, material, strength grade, surface finish, nut and washer combination, packaging method, and quantity. This lets the bolt be specified around the actual connection rather than forcing one generic configuration across different projects.

FAQ

What is the difference between DIN 933 and a partially threaded hex bolt?

DIN 933 refers to a hex head bolt with thread extending along the full shank length. A partially threaded bolt has an unthreaded portion of shank and is selected when the joint design calls for that configuration.

Can these bolts be used with hex nuts?

Yes. Full Thread Hex Bolts are designed for use with matching nuts. DIN 934 hex nuts can be specified when the assembly calls for a compatible standard hex nut.

Which material should I choose, carbon steel or alloy steel?

The selection depends on the required mechanical performance, operating condition, and project specification. Share the application and required grade so the appropriate material option can be quoted.

Are these bolts suitable for solar mounting structures?

They are suitable for fastening work in photovoltaic support and mounting assemblies when the selected size, material, finish, and mechanical requirement match the design of the system.

Can I order bolts with nuts and washers as a set?

Yes. Matching hex nuts and washers can be included in the supply scope according to the required assembly configuration and packaging method.

Do you support custom packing for distributors or project orders?

Packing can be arranged around the confirmed order requirement, including bulk packing, small boxes, labels, and complete fastening sets.
