Tension-Indicating Galvanized Steel Washer

Manufacturer part: 95318A120

Fasten structural screws and nuts securely without overtightening. When you see orange dye, you'll know you've applied the correct tension, so you don't accidentally strip threads. These washers distribute pressure under fasteners in columns, joists, and I-beams. They are tested and certified to meet industry standards for handling high-stress loads.Corrosion-Resistant Galvanized Steel—These washers combine the strength of steel with the rust resistance of stainless steel. They're an economical alternative to 18-8 stainless steel in wet and outdoor environments, but they won't hold up to salt water and chemicals.Medium Fastener Strength Rating—Rated Grade 5 or Class 8.8, these washers can be paired with medium-strength steel nuts and bolts without deforming. They are strong enough for most industrial applications, such as anchoring machinery and connecting pipe flanges.For Fastener Strength Grade/Class—If you require screws or nuts with a specific fastener strength rating, make sure your washer matches the grade or class.
