Key Features
- Exact Thread Specification — Cut to 3/8-16 thread pitch and 4-inch length, this screw threads directly into the designed mating point without reworking or shimming.
- Broad Genie Fitment — Compatible with GS-3390, GS-4390, and GS-5390 scissor lifts, GTH-636 and GTH-844 telehandlers, and the ZX-135/70 articulating boom lift.
- Structural Integrity Where It Counts — A fastener at this grade and size is typically used in structural or load-bearing joints; a stripped, under-spec, or corroded screw can compromise the assembly it secures and lead to costly structural failures.
A hex head cap screw is a fully threaded or partially threaded fastener driven by a wrench or socket, used to clamp two or more components together with controlled clamping force. When a screw of this type is damaged, corroded, or replaced with an under-rated substitute, the joint it secures can loosen, shift, or fail under load — making exact replacement with the correct grade and coating essential for safe machine operation.
