The surface is phosphated, appearing dark gray or black, and features a lubricating film. It has good wear resistance and rust prevention, and is economical in cost.
Black ISO 4017 Hex Bolt
Features a black oxide surface finish that offers a certain level of rust resistance; commonly used in general indoor environments or to meet custom color requirements.
Carbon Steel ISO 4017 Hex Bolt
The material is standard carbon steel (Q235 or 45# steel), representing a basic, general-purpose grade. It has moderate strength and high cost performance.
ISO 4017 Hex Screw with Blue White Zinc Plated
The surface features a blue-white zinc plating with a bright white finish and a slight blue tint. It has good rust resistance and is the most commonly used surface treatment for standard parts, suitable for general machinery and household appliances.
ISO 4017 Hex Screw with HDG
It is made using a hot-dip galvanizing process, resulting in a thick zinc layer. It has extremely strong corrosion resistance and is especially suitable for harsh environments such as outdoor areas, bridges, and power towers, with a long service life.
Grade 8.8 ISO 4017 Hex Bolt
Bystrong is a leading supplier of fully threaded hex head bolts in China. These products are performance grade 8.8, with thread sizes ranging from M1.6 to M64, and custom lengths are available.
ISO 4017 Hex Screw with Color Zinc
The surface is electroplated with colored passivation (yellow/rainbow color), resulting in a vibrant color. It offers superior corrosion resistance compared to blue-white zinc plating and is easily distinguishable, making it suitable for export products or applications with specific aesthetic requirements.

ISO 4017 Hex Screw: FAQ
ISO 4017 is a standard for fully threaded hexagonal head bolts published by the International Organization for Standardization (ISO). It specifies the thread dimensions, mechanical properties, and tolerance requirements from M1.6 to M64, and is one of the globally recognized basic standards for fasteners.
ISO 4017 bolts are used to create detachable, fastened connections between two or more components featuring holes. They pass through clearance holes in the parts being joined and are secured with a nut, or are screwed directly into a pre-threaded hole in one of the components; tightening or loosening is achieved by rotating the bolt head.
ISO 4017 bolts are widely used in:
- Assembly of various machine tools, engines, pumps, and valves.
- Bodies for commercial vehicles, agricultural machinery, and construction machinery.
- Construction and steel structures, pressure vessels.
- Fully threaded: Provides a greater clamping length.
- Wide range of materials: Available in carbon steel, stainless steel, and alloy steel.
- Internationally recognized: Globally accepted, easy to purchase and replace.
- Complete specifications: various diameters, lengths and strength grades (4.8~12.9).
- Surface treatments: Zinc-plated, hot-dip galvanized, Dacromet, black oxide, etc.
- High compatibility: Can be used with various types of hex nuts and washers.
ISO 4017 and DIN 933 are both standards for fully threaded hex bolts. Their dimensions are basically the same, and the main differences lie in the standard system, applicable specifications, and width across flats. They are generally interchangeable.
| Item | ISO 4017 | DIN 933 |
|---|---|---|
| Standard system | International Standard (ISO), or EN ISO 4017 in the European Union. | German National Standard (DIN) |
| Thread | Fully threaded | Fully threaded |
| Specification range | M1.6-M64 | M2-M52 |
| Alternative standard | ISO 4017 has gradually replaced DIN 933. | It has been replaced, but is still used in many situations. |

Pricing depends on specifications (diameter/length), strength grade, surface finish, and order quantity. Standard small-sized galvanized carbon steel items have a lower unit cost, whereas large-sized or high-strength (e.g., Grade 10.9/12.9) alloy steel products carry a higher unit price. Contact Bystrong today for a real-time quote.
- Nominal Diameter: M1.6 to M64
- Nominal Length: 2 mm to 500 mm (depending on the bolt diameter)
- Custom Sizes: For extra-long or oversized ISO 4017 hex bolts, please contact Bystrong for custom manufacturing services.
ISO 4017 hex bolts are inspected through comprehensive quality control procedures, including dimensional inspection using GO/NO-GO thread gauges, verification of head dimensions and bolt length, mechanical property testing (tensile strength, yield strength, hardness, and torque), surface quality inspection (coating thickness, salt spray corrosion resistance, and visual appearance), and material analysis using a spectrometer to verify the chemical composition. These inspections ensure the bolts comply with ISO standards and customer requirements.
ISO 4017 hex bolts should comply with ISO 898-1 for mechanical properties, ISO 68-1 and ISO 965-1 for thread dimensions and tolerances, and ISO 4042 for electroplated surface coatings. Reputable manufacturers also operate under ISO 9001 quality management systems and provide inspection reports to verify compliance. Bystrong supplies performance test reports with every shipment to ensure all products meet international quality standards.
An ISO 4017 hex bolt consists of a hex head, a bearing surface, a fully threaded shank, and a thread end. The hex head provides wrench engagement, the bearing surface distributes the clamping load, the fully threaded shank ensures maximum thread engagement, and the chamfered or flat thread end allows for easier installation. These components work together to provide a strong and reliable fastening solution.
