Q:Who is the information on fasteners ah?
Fastener production equipment (screw molding machine, cold heading machine, head machine, threading machine, cutting machine, thread rolling machine, rolling machine, drawing machine, wire drawing machine, screw automatic screening machine, vibration plate
Q:What are the technical requirements for fasteners?
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.
Q:In the fastener industry, 1018 refers to what material
Low-carbon steel. Domestic in accordance with the Japanese standard to create the SWRCH18A. (JIS G 3507) Carbon C: 0.15 to 0.20 Silicon Si: 0.17 to 0.37 Mn Mn: 0.60 to 0.90 Phosphorus P: ≤0.030 Sulfur S: ≤0.035 The carbon content of the material is relatively low and can not be quenched and tempered. Used for cold piers to make low-grade screws. Pull up the strength of 450Mpa.
Q:A194 GR3 is what style fasteners
A194 American standard I know is the US system, but now do not understand is GR3 in the end is what it means
Q:The difference between fasteners and standard parts
Fasteners are said from the point of view of the action, which contains both standard parts (GB ANSI ASME DIN EU JIS, etc.) and non-standard parts (according to the drawings) is not entirely a concept
Q:Bolts and other connection fasteners some points A B C grade what it means
Grade is not the same, the tolerance range is not the same, A-level tolerance of the smallest, C-class tolerance of the largest
Q:What are all the fasteners?
Go to the professional fastener website to learn it! Really too much, too hard to classify. I hope I can help you.
Q:Will the stainless steel fastening standard parts of the national standard code and name?
Because the fastener is a standard part, so the size of stainless steel fasteners and ordinary fastener size is the same, other standard GB / T 5267.4-2009 fastener surface treatment corrosion-resistant stainless steel passivation treatment
Q:What is the name of the screw (fastener)?
By specifications: M3. M4. M5. M6. M8. M10. M12 By head type: a. Flat head b. Small head (countersunk head)By the shape: a. Cylindrical light body b. Hexagonal c. Semi-hexagonal d. Cylindrical column posture
Q:High-strength screw standard parts of the quality of what data
Mechanical properties: hardness, tensile strength, etc. are in line with the standard requirements Size: size is in line with the standard requirements. Thread: through the rules are in line with the requirements.
