Xylan's versatility is best demonstrated as a coating for stud Bolts and nuts, where it provides unparalleled performance in ease of installation, corrosion resistance and ease of removal. It can be used on standard alloy steel nuts and bolts, or can be paired with stainless steel fasteners for even more benefits.
Xylan fastener coatings or "Blue Bolt Coatings" are typically specified in oil and waterworks applications.
A bolt’s function essentially boils down to applying a high enough Hose Clamps force that when external forces are applied, transverse movement and separation cannot occur. Using calibrated torque tools to tighten fasteners and apply that clamp force is far superior to going by the user’s judgement or feeling. Or, as one senior technician calls it “The One Grunt or Two Grunts Method”. Measuring torque alone, however, does not ensure a proper installation.
General commodity commercial fasteners do not fall under the umbrella of products that would require a UL listing or ICC-ES report. There are three main governing bodies that cover specifications for fasteners. ASTM (American Society for Testing and Materials) covers primarily bolts and fasteners for construction applications. SAE (Society of Automotive Engineers) covers fasteners for automotive, machinery, and OEM applications. ASME (American Society of Mechanical Engineers) standards B18.2.1 and B18.2.1 cover dimensional tolerances for square and hex head bolts, Screws, and Nuts. Mudge Fasteners provides fasteners to these three sets of specifications (ASTM, SAE, and ASME). A fourth specification group that is also applicable is AASHTO (American Association of State Highway & Transportation Officials). AASHTO specifications are typically only called out on highway projects and many AASHTO designations can be directly converted to an ASTM equivalent.
ICC (International Code Council) is the primary governing body responsible for writing and maintaining building, plumbing, mechanical, and fire codes adopted by local and state municipalities, and the federal government. ICC-ES (International Code Council-Evaluation Services, Inc.) is the branch of ICC responsible for performing technical evaluations of building products, components, methods, and materials to ensure that they meet the requirements of the codes. This evaluation process culminates in an ICC-ES report that provides evidence that the evaluated product or system meets code requirements. However, in the case of most anchor bolts and fasteners, the applicable sections of the codes (International Building Code, International Residential Code, International Property Maintenance Code, Etc.) direct you to the ASTM specifications covering said Anchors or fasteners. As the ASTM specifications already cover anchor bolts and fasteners in detail, there is no reason for ICC to write their own specifications for these items. For the same reason, ICC-ES does not need to perform evaluation testing of anchor bolts or fasteners. As long as the bolts meet the applicable ASTM specification(s), they will meet the applicable Code section(s).
When you are shortening bolt or Threaded Rods with a hacksaw, you always mangle the threads at the sawn end, making it difficult to get a nut threaded onto it. Reader Larry LeMasters tip produces a much better ending. Thread two nuts onto the bolt at the cutoff spot, tighten them against each other, then saw against the shoulder to create a clean right-angled cut. Next, loosen the nuts and file a slight bevel around the end to clear burrs created by sawing. Then spin off the nuts to clean and realign the threads. Your shorter bolt will work just like a new one from the box.
There are several distinct types of fastener, which may be referred to as a pin. These include small headless nails, sharpened pins used for holding fabrics while sewing, attaching paper to pinboards and the like, and several types of mechanical fasteners. Pins are an unthreaded mechanical fasteners, which are designed to be inserted through preformed holes.
Lock Washers and vibration-resistant washers are designed to prevent a threaded fastener from loosening. The terms are often used interchangeably. However, there is a difference.
Rivets are mechanical fasteners with a plain unthreaded shaft that are inserted through holes to join two or more parts together. A permanently formed head at each end prevents the rivet from removal from the hole. The shaft prevents any radial movements of the components. Depending on the type of rivet, and its ability to support shear load, it can resist considerable forces. The heads prevent axial movements of the parts, although less force is supported in this way.
