Cross-reference part number 237821GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- DIN 6921 Conformance, Class 8.8 Strength — Manufactured to the DIN 6921 hex flange head standard at property class 8.8, delivering the tensile strength the original design requires.
- Yellow Zinc (YZ) Finish — The factory-specified YZ coating provides corrosion resistance to match the original fastener's protective treatment.
- Direct OEM Replacement — This screw installs in place of the original without modification, maintaining the correct clamp load and seating against mating surfaces.
- Confirmed Fitment for the Z-80/60 — Designed specifically for the Genie Z-80/60 articulating boom lift, so you can order with confidence in compatibility.
- Genuine Genie OEM Part — Supplied as an authentic Genie component, ensuring dimensional accuracy across thread pitch, shank diameter, and head geometry.
A hex flange head screw combines a standard hex drive head with an integrated flanged bearing surface, eliminating the need for a separate washer and distributing clamping load evenly across the joint. The class 8.8 property rating indicates a high-strength fastener suited to structural and mechanical connections where consistent torque retention matters. A worn, stripped, or incorrectly graded screw in a critical joint can lead to loosening under vibration and load cycling — replacing it with the correct OEM part restores the integrity of the connection and keeps the assembly performing as designed.
