S-93493A349 0.156" ID x 0.438" OD MIL-I-24768/27 Plastic Washers

Key Features & Benefits at a Glance

• Superior thermal resistance withstands continuous exposure up to 280°F, ideal for high-temperature industrial environments
• Excellent electrical insulation properties prevent current leakage and short circuits in electrical assemblies
• Exceptional dimensional stability maintains precise fit with 0.156" ID and 0.438" OD under varying conditions
• Enhanced durability with Rockwell M100 hardness for reliable performance in demanding applications
• Corrosion-resistant fiberglass construction ensures long service life without degradation
• Regulatory compliance meets MIL-I-24768/27 specifications plus RoHS 3 and REACH environmental standards
• Optimized thickness range (0.054-0.070") provides consistent compression and load distribution

Professional Applications & Engineering Value

This fiberglass flat washer delivers critical engineering solutions where electrical insulation and thermal resistance are paramount. The light green fiberglass material provides non-conductive properties that prevent electrical arcing in panel assemblies, switchgear, and electronic enclosures. With a maximum temperature rating of 280°F, it maintains structural integrity in high-heat applications where metal washers would fail. The precise No. 6 screw size compatibility ensures perfect fitment in aerospace, military, and industrial equipment requiring MIL-I-24768/27 compliance. The combination of dimensional stability and corrosion resistance makes it ideal for harsh environments where chemical exposure or moisture would degrade standard washers.

Specification Summary & Compliance
