Overview – SCREW-HHC (1/2-13X7.0) 800-0109
The Cummins SCREW-HHC (1/2-13X7.0) 800-0109 is a direct replacement used in Cummins structural and equipment assemblies as the 1/2-13 x 7.0 inch hex-head cap screw, with no modification required at installation.
Parts Characteristics
A hex-head cap screw that clamps two components together to the specified preload, carrying the tension that holds an assembly true. It is the most-reused part in any teardown, so a correct grade and length keep the joint from working loose or overloading the threads.
Applicable Models & Applications
Used across Cummins assemblies specifying this 1/2-13 x 7.0 HHC screw. Match the grade, thread and length against your old screw – fasteners that look alike differ in proof load and how they hold preload.
Maintenance & Replacement
Replace fasteners as a matched set at every teardown. A new screw into a stretched or galled old thread seats poorly and walks loose under vibration.
Confirm the grade matches the specification, not just the head shape. A screw that looks right but is the wrong grade loses preload and the joint drifts.
Torque to the figure the joint calls for, with the right lubricant on the threads. A screw torqued dry or to the wrong value either snaps or never clamps.
Keep the common HHC screws for your assembly on the bench. They are cheap, they are load-critical, and an assembly loose on a screw is a machine waiting on a small part.
Price Reference (USD)
Budget roughly USD 1 to USD 8 for a SCREW-HHC (1/2-13X7.0) 800-0109; volume orders and stock status can move this range either way.
