Bolts

Hex Head Bolts

● Designed with smooth rolled threads forbetterclamp load, shear resistance and resistance to stripping.

● Made of fine grain steel fora more uniform micro-structure, resulting in improved toughness and fracture resistance.

● Inch Bolts

■ Meet orexceed SAE Grade 8 specifications fortensile strength and proof load, minimum tensile strength of 150,000 psi.

■ Have 20% higherhead height than SAE specifictions forlonger wearlife, easiergripping and less slippage.

■ Marked with 6 radial dashes on the bolt head.

● Metric Bolts

■ Meet orexceed ISO Class 10.9 specifications fortensile strength and proof load, minimum tensile strength of 150,000 psi.

■ Marked with 10.9 on the bolt head.

● Bolt Coatings

■ Phosphate and Oil coating provides betterclamp loads and torque retention.

■ Zinc Dichromate plating provides betterlong term corrosion resistance.
