FAQS on 3 8 washers

以下是为核心关键词[3 8 washers]及相关术语创建的5组英文FAQ问答，使用HTML富文本格式：

Q: What are the specifications of 3/8 washers?

A: 3/8 washers refer to flat washers designed for 3/8-inch diameter bolts. Common materials include carbon steel, stainless steel, or specialty coatings. Typical ID (inner diameter) is 0.406" and OD (outer diameter) ranges from 0.75" to 1".

Q: How do case hardened washers differ from standard 3/8 washers?

A: Case hardened washers undergo heat treatment for superior surface hardness (up to HRC 50+), while standard 3/8 washers have no hardening. This creates a wear-resistant shell that prevents bolt embedding under heavy loads. They're ideal for high-torque applications in machinery.

Q: Are black oxide stainless steel washers corrosion resistant?

A: Yes, black oxide stainless steel washers combine stainless steel's natural corrosion resistance with an additional black oxide layer. The electroplated coating enhances saltwater/chemical resistance while reducing light reflection. They maintain corrosion protection even if scratched.

Q: When should I use black stainless steel flat washers?

A: Use black stainless steel flat washers in visible applications needing corrosion resistance and aesthetics. The PVD-coated black finish won't chip like paint and provides uniform coloration. Suitable for marine hardware, outdoor fixtures, and architectural projects.

Q: Can all 3/8 washers handle high-temperature environments?

A: Standard carbon steel 3/8 washers degrade above 400°F, while black oxide stainless steel variants withstand 800°F. For extreme heat (1200°F+), use case-hardened alloy washers. Material selection directly impacts thermal performance.
