Characteristics of

WANHAO Hexagonal pin

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.
