Description

The 920489 Cap Screw by Blackmer

The 920489 Cap Screw is a high-precision fastener designed for use in positive displacement and sliding vane pumps. Constructed from durable steel alloy, it features a corrosion-resistant coating to withstand challenging operating environments, ensuring long-term reliability and performance.

Its dimensions include a 1/2-inch diameter with a 2-inch length, compatible with specific pump models requiring this standard size. The cap screw's thread pitch is 13 TPI (threads per inch), which aligns with industry standards for pump assembly components.

Features of the 920489 Cap Screw include a hexagonal head for easy tool engagement, high tensile strength rated at 120,000 psi, and a standard metric coarse thread. It is engineered to provide secure fastening in pump housings and impellers, minimizing vibrational loosening during operation.

This cap screw is ideal for maintenance professionals, pump assembly technicians, and OEMs working on models compatible with this part number. It is suitable for applications where precise fit and reliability are critical, including industrial fluid handling, chemical processing, and water treatment facilities.

The 920489 Cap Screw ships individually and does not include additional hardware or washers. It is recommended to replace with exact OEM parts during routine maintenance or repair to ensure optimal pump performance.

To maintain the integrity of the cap screw, it should be inspected regularly and torqued according to manufacturer specifications. It can be cleaned with standard maintenance solvents and should be stored in a dry, protected environment to prevent corrosion. The manufacturer warrants the cap screw against manufacturing defects for a period of one year from purchase.
