Product description
Medium-Strength Metric Class 8.8 Steel Square-Neck Carriage Bolts
These Class 8.8 steel bolts are suitable for fastening most machinery and equipment.
They have a zinc or zinc yellow-chromate plating to resist corrosion in wet environments.
A square neck keeps them from turning when tightening a nut. A smooth, rounded head provides a finished look.
Length is measured from under the head.

Timing Belt Failure Analysis
1. Heat Degradation
Appearance: Cracking from high temperature operation, rubber
Cause
When rubber belts operate at elevated temperatures (greater than 185掳F) for prolonged periods of time, the rubber compound gradually hardens resulting in back cracking due to bending.
These cracks typically remain parallel to the belt teeth and usually occur over land areas (in between belt teeth), as illustrated in picture. Belts generally fail due to tooth shear, which often leads to tensile cord fracture.
Solutions
To determine if a special high-temperature belt construction will improve the belt performance in specific applications, contact a Pioneer Representative.
2. Foreign Objects
Appearance: Tensile cord failure from debris
Cause
The introduction of foreign objects between a belt and sprocket often damages both belt teeth and tensile cords.
Tensile cords often fracture internally (see Figure 3) or fail later due to crimping, as shown in Figure 4. Once a portion of the tensile cords have fractured, the remaining tensile strength of the belt has been reduced considerably.
Solutions
If belt damage from debris is noticeable, the belt should be replaced and the sprockets checked for damage. Damaged sprockets should also be replaced.Automotive Belts manufacturers
