FAQS on 4 washer diameter

Q: What is the standard outer diameter of a 1/4" washer?

A: A standard 1/4" washer typically has an outer diameter of approximately 0.75 inches. This measurement may vary slightly depending on manufacturer specifications. Always confirm dimensions for critical applications.

Q: How does an 8 washer diameter differ from a 4 washer diameter?

A: An 8 washer diameter refers to a larger outer dimension than a 4 washer. For example, a 8 washer may measure ~0.38" ID and ~0.75" OD, while a 4 washer is smaller. Size numbering often correlates with screw sizes.

Q: What does "7/8 inside diameter washer" mean?

A: A 7/8" inside diameter (ID) washer has a central hole measuring 7/8 inches. The outer diameter (OD) will be larger, such as 1-3/4" for heavy-duty applications. ID ensures compatibility with bolt or screw sizes.

Q: How do I measure a 4 washer diameter accurately?

A: Use calipers to measure the washer's outer edge for OD and inner hole for ID. For a 4 washer, expect ~0.25" ID and ~0.5" OD. Verify against ANSI/ASME standards if precision is required.

Q: Can a 7/8 ID washer fit a 4 washer diameter bolt?

A: No, a 7/8" ID washer is too large for a 4 bolt (designed for ~0.25" ID). Match bolt diameter to the washer's inner diameter to ensure proper load distribution. Mismatched sizes reduce effectiveness.
