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.
Complete
Fastening
System
For better assurance and
to get the maximum
resistance and duration
use WANHAO HD nuts and
washers in combination
with WANHAO fasteners.
