Series 640 Puller Lower Hook Block Screw - Black

Product Description

This black CM screw is a replacement fastener for the lower hook block assembly of compatible Series 640 pullers. Part number 940812 is identified by industrial distributors as a lower hook block screw and is also referenced by CM component designation 640-162.

The screw secures the associated lower hook block components in their intended assembled position. Its manufacturer-specific configuration makes it suitable for compatible CM pullers rather than as a general-purpose replacement fastener.

This component can be used when the original screw is damaged, stripped, corroded, missing, or unsuitable for reuse during hook block servicing. Published compatibility listings identify models 4043, 4045, 4047, 4050, 4051, 4060, 4062, and 4065.
