Characteristics of

 

WANHAO Hexagonal Bolts

 

Higher Head

 

Heads 20% higher than American Standard B 18.2.1. Providing

 

increased fatigue life and maximum holding force for the nut.

 

SAE Grade Brands

 

The radial marks indicate the grade of SAE strength for better

 

identification. Six marks on the head guarantee the quality

 

grade 12.9 / 35-38 Rockwell (113/124 Kg./mm2)

 

Forged Head

 

Provides a correct flow of the steel fibre reducing the fatigue

 

points ensuring major resistance to bumps and an even

 

distribution of the weight. The edges do not round off and the

 

bolts can be reused. The washer sits perfectly below the head.

 

Laminated Thread

 

Laminated with the maximum precision they provide a better

 

hold eliminating the risk of breaking.

Fastening

 

System

 

For better assurance and

 

to get the maximum

 

resistance and duration

 

use WANHAO HD nuts and

 

washers in combination

 

with WANHAO fasteners.
