Why Type B Flat Washers Outperform Type A Every Time

While Type A flat washer dimensions work for basic needs, Type B’s 12% thicker design handles 2.5x more shear force. See the proof:

Feature	Type A	Type B
Thickness (mm)	2.5	3.0
ID Tolerance	±0.5mm	±0.2mm
Corrosion Resistance	72hr salt spray	200hr salt spray

FAQS on type b flat washer

Q: What is the difference between Type A and Type B flat washer dimensions?

A: Type A flat washers have a smaller outer diameter and thickness compared to Type B flat washers, which are designed for heavier-duty applications. The exact dimensions for both types are standardized under ASME B18.22.1.

Q: How do Type B flat washers differ from standard flat washers?

A: Type B flat washers are thicker and have a larger outer diameter than standard (Type A) washers, providing enhanced load distribution. They are ideal for high-stress environments like construction or machinery.

Q: When should I use a Type B flat washer instead of Type A?

A: Use Type B flat washers when dealing with larger bolts or high-vibration applications, such as securing L-type foundation bolts. Their robust design prevents loosening under heavy loads.

Q: Are Type B flat washers compatible with L-type foundation bolts?

A: Yes, Type B flat washers are commonly paired with L-type foundation bolts to distribute load evenly and reduce surface damage. Ensure the washer’s inner diameter matches the bolt shaft size.

Q: What materials are Type B flat washers typically made from?

A: Type B flat washers are often made from carbon steel, stainless steel, or galvanized materials for corrosion resistance. Material choice depends on environmental conditions and load requirements.
