• Non-standard Fastener

    Non-standard Fastener

    Non-standard fasteners refer to fasteners that do not need to correspond to the standard, that is, fasteners that do not have strict standard specifications, can be freely controlled and matched, usually by the customer to put forward specific requirements, and then by the fastener manufacturer Based on these data and information, the manufacturing cost of non-standard fasteners is generally higher than that of standard fasteners. There are many types of non-standard fasteners. It is because of this characteristic of non-standard fasteners that it is difficult for non-standard fasteners to have a standardized classification.
    The biggest difference between standard fasteners and non-standard fasteners is whether they are standardized. The structure, size, drawing method, and marking of standard fasteners have strict standards set by the state. (Parts) parts, common standard fasteners are threaded parts, keys, pins, rolling bearings and so on.
    Non-standard fasteners are different for each mold. The parts on the mold that are in contact with the product glue level are generally non-standard parts. The main ones are the front mold, the rear mold, and the insert. It can also be said that apart from screws, spouts, thimble, aprons, springs, and mold blanks, almost all are non-standard fasteners. If you want to purchase non-standard fasteners, you should generally provide design input such as technical specifications, drawings and drafts, and the supplier will evaluate the difficulty of non-standard fasteners based on this, and preliminary estimate the production of non-standard fasteners. Cost, batch, production cycle, etc.

    carriage bolt

    A carriage bolt (also called coach bolt and round-head square-neck bolt) is a form of bolt used to fasten metal to metal or, more commonly, wood to metal. Also known as a cup head bolt in Australia and New Zealand.


    It is distinguished from other bolts by its shallow mushroom head and the fact that the cross-section of the shank, though circular for most of its length (as in other kinds of bolt), is square immediately beneath the head. This makes the bolt self-locking when it is placed through a square hole in a metal strap. This allows the fastener to be installed with only one tool, a spanner or wrench, working from one side. The head of a carriage bolt usually is a shallow dome. The shank has no threads; and its diameter equals the side of the square cross-section.

    The carriage bolt was devised for use through an iron strengthening plate on either side of a wooden beam, the squared part of the bolt fitting into a square hole in the ironwork. It is common to use a carriage bolt to bare timber, the square section giving enough grip to prevent rotation.


    The carriage bolt is used extensively in security fixings, such as locks and hinges, where the bolt must be removable from one side only. The smooth, domed head and square nut below prevent the carriage bolt from being unlocked from the insecure side



    A nyloc nut, also referred to as a nylon-insert lock nut, polymer-insert lock nut, or elastic stop nut, is a kind of locknut with a nylon collar that increases friction on the screw thread.
