Engineering Advantages

The Conical Knurled Spring Washer is engineered to address critical challenges in mechanical fastening. Its conical spring design, combined with a 360° knurled contact face, provides 200% greater anti-vibration force compared to conventional serrated washers. This makes it ideal for applications where dynamic loads and thermal cycling are prevalent.

The radial knurling on the locking mechanism ensures a secure grip without requiring pre-drilling, a feature that significantly reduces installation time and prevents galling on soft metals. According to NIST standards for material testing, NIST emphasizes the importance of surface finish and material compatibility in preventing galling, which this washer addresses through its proprietary design.

Material Science and Durability

Constructed from 304/316 stainless steel, the washer meets stringent corrosion resistance standards. The 316SS variant, in particular, offers exceptional performance in harsh environments, with a salt spray resistance of over 500 hours as per NIST guidelines for ASTM B117 testing. This makes it suitable for aerospace, marine, and chemical processing applications where exposure to corrosive elements is common.

The material's temperature tolerance, ranging from -55°C to +300°C, ensures reliability in extreme conditions. NIST's research on material behavior under thermal stress underscores the importance of such specifications, as highlighted in their publications on high-temperature alloys.
