Q: what parts do Fasteners include: A type of fastener that has no head and only the ends that are threaded at both ends. When connected, it must be screwed into the part with internal screw hole, the other end through the through hole with the parts, and then screw the nut, even if the two parts fastened into a whole. This type of connection is called a stud connection and is a detachable connection. Mainly used for connecting parts of a larger thickness, requiring a compact structure, or because of frequent demolition, should not be used bolted connection occasions.

Q: High-strength screw standard parts of the quality of what data: High strength bolts are made of high strength steel, or bolts that require greater preload. High-strength bolts are tightened with a special wrench nut, the bolt has a huge and controlled pre-tension, through the nut and the pad, the connector also produced the same size of the pre-pressure.

Q: Bolts and other connection fasteners some points A B C grade what it means: Bolts and other fasteners connected due to a wide range of applications, the product level requirements are different, so the bolt product grade is divided into A, B, C three grades. One of the most accurate A, C level of the most inaccurate, B between the two. Class A is used for important applications where assembly accuracy is high and subject to greater impact, vibration or variable loads. Class A for d = 1.6-24mm and l ≤ 10d or l ≤ 150mm bolts. B grade for d> 24mm or l> 10d or l ≥ 150mm bolts, thin rod B grade M3-M20 hexagonal flange bolts, anti-loose performance better. Class C is between M5 and M64.

Q: Who is the information on fasteners ah?: Fastener materials (steel wire, stainless steel wire) Fasteners use tools, fastening systems.

Q: For the commonly used standard parts, for some of the quality of good or bad, how to distinguish,: If it is important, random to do one or two destructive pull test, their own press with a simple tooling, pay attention to safety, if their own, to the physical and chemical test units or heat treatment of the brothers can do. You can also go to the supplier to monitor the sampling of such a similar test (contract agreed).

Q: What is the name of the screw (fastener)?: Screw, it was also called "screw" [screw], "screw" (screw). In fact, the screw is known, and the screws, screw rods are different from each other. Screws are generally called wood screws; is the tip of the kind of tip, pitch larger, generally used to tighten wood parts, plastic parts. Screw is a screw (mechanical screw), is the front of the kind of flat head, pitch is small, uniform, generally used to fasten the metal, machine parts.

Q: Does the fastener include screws?: Fastener fasteners are also known as standard parts on the market and are a generic term for a class of mechanical parts that are used when two or more parts (or components) are tightly connected as a unit. It is characterized by a wide variety of specifications, performance purposes vary, and standardization, serialization, the degree of generalization is very high. Fasteners are the most widely used mechanical base pieces and are in great demand.

Q: What are all the fasteners?: Of course, there are many categories of fasteners, in short, there are many, many of the fasteners.

Q: Will the stainless steel fastening standard parts of the national standard code and name?: Fasteners with the material does not matter the standard, and now the most commonly used national standards and names corresponding to the following GB5783, full-tooth hexagonal screws GB70, hexagonal hexagon head screw GB818, pan head cross slot screw GB819, countersunk head cross slot screw GB845, pan head cross slot self-tapping nail GB846, countersunk head trough self-tapping nail GB6170, ordinary hexagonal nut GB889, nylon lock nut GB96, flat pad GB93, spring pad GB869, countersunk head rivets

Q: Our company to purchase a number of fasteners to see when the CAD drawings in the technical requirements I do not know the specific to write those content: 1, the product used by the material (the available material is too much to see what your company to ask) 2, the accuracy of the thread (bolt type of external thread is generally 6g, nut class internal thread is generally 6h) 3, surface treatment Stainless steel materials generally do not do treatment, carbon steel, color, galvanized, Dacromet, nickel, chrome, etc.) 4, product tolerances before the surface treatment or surface treatment of the above is the standard parts of the standard, But also depends on the actual use, we must deal with the landlord.
