The Specification of CNC Shoulder Throttle Lever Bolts

August 05, 2023

The specifications of CNC shoulder throttle lever bolts can vary depending on the specific application and manufacturer. However, here are some common specifications you may come across:

Material: CNC shoulder throttle lever bolts are typically made from high-strength materials like stainless steel, alloy steel, or carbon steel. The specific material selection depends on factors such as the required strength, corrosion resistance, and environmental conditions.

Thread Type: These bolts usually have a machine screw thread, with common thread types including metric (such as M6, M8, or M10) or imperial (such as 1/4", 5/16", or 3/8"). The thread type and size need to match the corresponding threaded holes or inserts in the throttle lever and mounting bracket.

Shoulder Diameter: CNC shoulder throttle lever bolts have a shoulder or collar that acts as a stopper. The diameter of the shoulder is designed to fit precisely into the corresponding hole or recess in the throttle lever assembly, providing stability and support.

Shoulder Length: The length of the shoulder determines the extent to which the throttle lever can be moved before reaching the stopper point. It is important to choose a bolt with an appropriate shoulder length based on the required range of throttle movement.

Overall Length: The overall length of the bolt is measured from the underside of the head to the bottom of the threaded portion. It should be chosen based on the thickness of the components being fastened together.

Head Type: CNC shoulder throttle lever bolts typically have a hexagonal head (hex head) for easy tool access and tightening. The head size should be compatible with the appropriate hex key or wrench.

Coating/Finish: Some CNC shoulder throttle lever bolts may have coatings or surface finishes to enhance corrosion resistance, aesthetics, or provide additional lubricity. Common coatings include zinc plating, black oxide, or passivation for stainless steel bolts.

Strength Grade: The strength grade or class of the bolt indicates the level of tensile strength it possesses. Common grades for shoulder throttle lever bolts include 8.8, 10.9, or 12.9, with higher numbers indicating higher strength.

It is important to consult the manufacturer or supplier for specific specifications and recommendations based on your application requirements. Additionally, following the manufacturer's guidelines for installation torque and usage limitations is crucial for optimal performance and safety.
