Engineered for Precision and Strength

When maintaining or repairing your Husqvarna garden tractor, every component counts—especially the bolts that hold key parts together. This Grade 8 Left-Hand Thread Bolt (3/8-24 x 1.25) is built for superior durability and secure fastening in high-stress areas. Designed to withstand significant torque, this bolt is a vital piece of hardware in the drive system and other rotating components of your garden tractor.

High-Strength Left-Hand Thread Design

What sets this bolt apart is its left-hand thread (LHTHRD) configuration. Unlike standard right-hand threads, this bolt tightens counter-clockwise, making it perfect for rotating parts that might otherwise loosen under normal operation. Whether you’re replacing worn hardware or upgrading critical fasteners, this Grade 8 bolt ensures everything stays securely in place.

With dimensions of 3/8″-24 UNF thread pitch and 1.25″ length, it fits precisely where OEM specs demand high tension and anti-loosening reliability. Additionally, its Grade 8 rating guarantees optimal tensile strength and toughness, even under constant vibration or load.

Lightweight but Strong Packaging

Despite its high-performance build, this bolt is lightweight and easy to handle. The gross weight is only 30 grams, making it simple to store, ship, and install. It comes in compact packaging with dimensions:

• Width: 47 mm

• Length: 17 mm

• Height: 17 mm

This compact size means you can stock several in your toolkit without taking up unnecessary space.
