The value is 9 millimeters, classifying it as a small-diameter high-strength bolt.
Installation and Inspection Characteristic
The "torsional shear type" design.
Material and Surface Treatment
Pertains to durability and basic rust prevention. The bolt material is typically alloy steel (e.g., 35VB).
Design Purpose
Specifically designed for critical connection points in light steel structures that require high reliability, precise preload, and ease of quality inspection.

Frequently Asked Questions
What does the model "JSS II 09 S10T" specifically represent? What are the key parameters?
This model number identifies the product's core specifications:
JSS II: Series code compliant with Chinese standards for high-strength torsional shear bolts
09: Nominal diameter of 9 mm
S10T: 10.9 property class with torsional shear type installation
What types of projects or connection areas is this bolt primarily used for?
Specifically designed for light steel structure joints requiring high reliability and precise pre-tensioning force.
How is product quality and compliance guaranteed? Are there relevant certifications?
As a critical load-bearing component, qualified products provide material certificates, mechanical performance test reports, and proof of standard compliance.
What are the special benefits of the "torsional shear type" for construction and inspection?
This feature enables "inspection during construction":
Simple Installation: Special electric wrench tightens until the hexagon pintail shears off
Intuitive Inspection: Pintail shearing provides visual confirmation of proper final tightening
Efficient Quality Control: Eliminates need for additional torque wrench re-inspection
What information needs to be provided during procurement?
Please specify: complete product name and specifications, material requirements, surface treatment, and packaging preferences.
What is the core difference between it and ordinary 10.9-grade high-strength bolts?
The core difference lies in the installation quality control method. Torsional shear bolts control pre-tension objectively through physical shearing, offering higher reliability and more convenient inspection compared to subjective torque-based methods.
