Description
Overview
The short stud plays a vital role in fastening gearbox casings and driveline hardware on marine vessels. It delivers secure clamping in vibration-heavy conditions found on both small craft and commercial boats. Because it uses a 1/2″ UNC thread form and measures 4-1/4″ overall, installers can apply repeatable torque with confidence. Argomarine lists this component as AM1082, which ensures simple identification in workshop notes and service records. This short stud suits marine gearbox maintenance and overhauls where reliability matters.

Specifications and Materials
This short stud features a 1/2″ UNC thread profile, known for durability and ease of engagement. The length measures 4-1/4″, making it suitable for most gearbox case locations. Always apply anti-seize or threadlocker when specified, and tighten to the torque recommended by the gearbox manufacturer.

As a result, technicians can check pitch and diameters against industry standards with ease.
Compatibility and Fitment
Use this stud in gearbox assemblies designed to accept 1/2″ UNC fasteners. It threads directly into tapped gearbox cases or backing plates. In addition, the stud format assists with alignment during reassembly, which reduces installation errors. Confirm the stud length against technical drawings to ensure proper engagement and safe protrusion for hardware. If your service manual specifies AM1082, this is the correct part.
Compliance and Safety
Follow torque and tightening sequences as outlined by gearbox manufacturers. Wear gloves and eye protection at all times. Furthermore, clean threads thoroughly and check for galling or corrosion before fitting. Replace worn or damaged fasteners immediately rather than attempting to repair them.
Marine Applications
Boat owners and repairers frequently use this short stud to mount gearbox main cases to supports or brackets. It also proves useful in driveline service tasks that require repeatable alignment. Consequently, the stud’s design makes assembly easier in cramped engine bays where bolts may prove difficult to position.
