Various different types of hex bolts are available, each best suited to different applications and environments. Fully-Threaded Hex Bolts Fully-threaded hex bolts are threaded from the end of the bolt right up to the head. The following sections provide further detail on some of the key hex bolt types, giving you the knowledge you need in order to make a fully-informed buying decision. : 007-988-521-6580 Email: william.choi@Rs-components.com (,), Raspberry Pi, Arduino & Development Tools, Engineering Materials & Industrial Hardware, Development Tools & Single Board Computers, Industrial Push Buttons, Pilot Lights & Control Stations, Pneumatic Counters, Logic Controllers & Timers, Electronics Cleaners & Protective Coatings, Electronics Components, Power & Connectors. As a guideline, the higher the number, the stronger the steel. Click here to download a PDF of our Engineering Catalogue. Choosing the right-sized hex bolt for your task is important, and there are several factors to take into consideration when measuring hex bolt dimensions and sizes. Hex bolts are typically manufactured from steel or stainless steel. Both fully-threaded and partially-threaded hex bolts are available. These provide various qualities and appearances in order to suit a wide range of applications. To receive useful info and product updates add your details below. Click here dot download a PDF of our Construction Catalogue. These are as follows: The length of the bolt (measured from the end of the bolt up to under the head), Thread size (the size of the thread, typically using ISO metric or M-style measurements), Thread pitch (the number of threads per inch the finer the bolt, the more threads per inch and the higher the thread pitch). This number indicates the outer diameter of the thread, measured in millimetres. As a result, hex bolts are a widely used staple fastener. This catalogue includes stainless/galvanized fasteners and fittings, and construction brackets. hexagonal head and have a plain shank between the base of the head This size chart focuses on DIN standard 931 bolts (hex bolts which have a partially-threaded clear shank along the length of the body). It uses rotational force to drive the bolt firmly and securely into place, helping to provide easier entrance and exit into the material whilst also providing added grip. Properly installed fully-threaded hex bolts are designed to spread the pressure across the full length of the bolt, providing a greater level of strength than partially-threaded alternatives. classes of either Class 50,70,80 (304 and 316 - but depending on Hex bolts are a type of threaded bolt, characterised by their six-sided hexagonal-shaped head. Example hex bolt uses include hex head screws for wood, metal, and many other environments and scenarios. Hex Bolt, meaning its thread begins under the hex head and is Their primary use is for heavy-duty fixing and fastening applications. The following hex bolt size charts should help you to easily select the most suitable product for your requirements. This catalogue includes stainless fasteners and fittings, marine hardware and construction brackets. tables below for head dimensions, thread pitch and lengths. They can then be tightened using a range of tools including a hex bolt wrench, socket sets, spanners, hex keys, and ratchet spanners. They offer strong tensile properties and most standard types can be used in multiple locations (dependent upon the material and finish). and where the thread begins. size) or Class 100 (Bumax). Understand what hex bolts are, their uses, how they work, their materials, and the different sizes available. Although brass provides a high level of resistance against corrosion, it is usually more expensive so is often overlooked in favour of steel. Hex Head Bolts (also known as Engineers Bolts) have a An unthreaded shank (also known as grip length) joins the threaded shank and the head. continuous along the full shank of the bolt. Partially-Threaded Hex Bolts Partially-threaded hex bolts are only threaded from partway down the bolts length to the end. See Stainless Bolt Strength Data. Partially-threaded bolts provide strong levels of resistance. Refer to the The ISO metric thread size system is widely used around the world. Hex bolts made from stainless steel can be used in either internal or external applications, but zinc-plated steel is another common alternative well-suited to indoor uses. You may also find hex bolts made from other materials like brass, but this is less common. As a result, it can be difficult to locate an accurate chart which covers a range of hex bolt types and sizes. This additional size chart is intended for use with DIN standard 931 bolts (hex bolts which have a completely threaded shank). Strain on the unthreaded part of the shank is prevented by the design which ensures that section has no weak spots. Hex bolts can be categorised in a number of different ways chiefly their sizing, the material or finish used in their manufacture, and whether they are fully or partially threaded. It is a handy international standard for measuring thread sizes across an array of different screw and bolt types. Hex bolts are sometimes also known as hex head bolts or hexagon bolts, again due to their distinctive head shape. Request a copy of our Engineering & Marine, or Construction Wall Chart. This makes their installation and removal a straightforward process, plus ensuring it is also easy to loosen or tighten hex bolts once they are in situ. The hexagon-shaped head ensures that it is easy to grip hex bolts from multiple angles, using different types of tool. This could include: During the erection, repair, and maintenance of buildings, bridges, and road infrastructure, Woodworking tasks such as fastening frames. Anzor Christchurch is moving to 401 Blenheim Road, Upper Riccarton, Anzor Napier has moved to 51 Edmundson Street, Onekawa. Hex head bolts are versatile and adaptable fasteners, making them suitable for a variety of uses across a range of industries and applications. Hex bolts can be either fully threaded or partially threaded (featuring a clear shank along part of the body) and are suitable for use in a wide range of applications, typically machinery and construction. NZ's Largest Range of Stainless Fasteners. Steel is available in varying strengths and grades typical standards for steel hex bolts include EN8 steel and EN16 steel. The thread of a hex head bolt, also known as the screw thread, is the helical structure which comprises the main body of the bolt. Additionally, different coatings and finishes are available. As an example, a hex bolt with a thread size of M8 would have an outer diameter of 8mm. They are ideal for use in heavy-duty fastening applications and are best suited to installation in pre-threaded holes. They are available in a choice of types, sizes, materials and finishes, providing the freedom and flexibility to select the bolt best suited to your particular task or application. Each size is denoted by the letter M followed by a number. You are subscribed to push notifications but they are not enabled in your browser. While some manufacturers offer hexagonal bolts made from other materials, steel and stainless steel hex bolts are the norm. Hex bolts can be used either in pre-tapped holes or with nuts, depending on the application. Free gun with every full bucket of fischer injection mortar purchased! Hex Head Setscrews can be described as a fully threaded The Hex Bolt and Setscrew range are made to tensile strength Click through to shop some of the most common hex bolt thread sizes: Most hex bolt size charts refer to a specific range of products. Stainless steel is another popular choice for hex bolts thanks to its strong corrosion-resistant properties.
