Hex Bolts have a hexagon head part thread and part shank and is used to fasten material together by inserting the bolt from the one end and securing it with either a nut on the other end or into a taped hole. A nut and bolt combination compresses everything together. To tighten the nut requires a socket and wrench or a spanner If while tightening the nut the bolt turns with it a second spanner or wrench is required to hold-on to the bolt while the nut is tightened. If thread length is critical there is a cross over where a hex bolt could be fully threaded. This is due to a gradual change in the fastener industry due to wholesalers wanting to reduce their stock holdings now they only carry the shorter lengths as fully threaded. Designed to be used in all conditions. The best fastener for marine coastal chemical and food environments. Stainless steels are largely non-magnetic but it is common for stainless steel fasteners to show a small degree of magnetism which is a result of work-hardening during the manufacturing process Can Stainless corrode?: Stainless steel is corrosion-resistant but not corrosion-proof and corrosion can occur if the material is installed or handled incorrectly. The use of tools and drills made from conventional steel during the installation of stainless steel fasteners may also lead to problems. Even the hardest of tools can produce debris that leaves minute steel particles on the stainless steel fastener surfaces or in pre-drilled holes. It is these particles that often rust when exposed to moisture or oxygen and can result in a stained or tarnished finish to the stainless steel material Grade v Class Difference: Imperial fastenings are referred to as grades and metric fastenings are referred to as classes. Both have marking systems that make it possible to determine grade and class. An example is a ½” UNC bolt with 5 lines on the head is grade 8 and 3 lines is grade 5 both are regarded as high tensile. Metric bolts are slightly different if it has 4.6 then it is mild steel and 8.8 is high tensile. The markings on a stainless fastener indicate the grade of material and strength e.g. material G304 grade will have one of the following markings: A2-70 G304 A2 304 and G316 grade stainless will have one of the following: A4-70 G316 A4 316 Thread Pitch (Metric): Pitch means the distance between the peaks of two threads along a screw bolt or fastener expressed in millimetres (mm). Used when referring to Metric parts. For example a thread pitch of 1.50mm means that the distance between one thread and the next is 1.50mm Fastener length: is generally measured from the point where the surface of the material will be when the fastener is installed to the end of the fastener. All material is advisory only and its use by anyone is entirely voluntary. Reliance on it for any purpose by anyone is at the sole risk of that person and Bolt and Nut Australia is not responsible for any loss claim or damages arising therefrom.
