Description
The Kurt SKOAM20.22 sine key pair is a metric, non-expandable O-ring-style locating key sold in matched pairs for precise alignment in vise setups. Each SKOAM20.22 key is made with strict dimensional tolerances to ensure consistent workholding and precise vise alignment during machining tasks. This 20mm x 22mm sine key pair is designed for applications requiring accurate part indexing and repeatable setup to reduce rework and cycle time. The design is non-expandable to ensure radial stability and location under clamp loads commonly encountered in milling and drilling. Technicians and Maintenance personnel will find the Kurt vise sine key pair straightforward to install and inspect during preventive maintenance. Material selection and machining ensure that the keys resist wear while maintaining the datum relationships required for precision work. The SKOAM20.22 is ideal for jigging, fixture alignment, and high-repeatability fixturing tasks that require a compact, metric sine key solution. Dimensions: B = 20 mm, C = 22 mm, A (Theta) = 0.625". Each set contains two pieces for matched-pair performance.
Product Features and Benefits
Matched metric sine key pair for repeatable locating
Sold in pairs and finished to tight tolerances, the Kurt SKOAM20.22 ensures consistent datum contact for repeatable setups.
Non-expandable O-ring style for stable positioning
The non-expandable O-ring configuration prevents radial growth under load, preserving vise alignment and reducing part movement.
Compact 20mm × 22mm form factor
This 20 mm x 22 mm sine key (pair) has a small footprint, making it ideal for use in confined vise jaws while still providing sufficient contact area for secure workholding and locating.
Durable machined construction for long service life
Precision machining and material selection reduce wear and help maintain accurate locating features over repeated cycles.
Direct fit for Kurt vise locating applications
Designed for use as a Kurt vise sine key pair, it integrates cleanly with existing locating grooves and standard vise tooling.
