EARTHMOVING FASTENERS

The online catalogue provides the entire range of product available for earthmoving machinery.

 
Track bolts are generally hexagon domed head bolts. They are used to secure the track plates to the track chains on crawler equipment such as bulldozers. Ajax track bolts are forged from alloy steels and heat-treated to the specifications of the original equipment manufacturers.
A tensile strength of 170,000 lbf/in2 provides 14% more clamping force that SAE J 429 Grade 8. Impact resistance is greatly improved by tempering and fatigue resistance reduced by having rolled threads and a smooth under-head radius. Some bolts may be heat-treated to 185,000 lbf/in2 depending upon the requirements of the application.
Track bolts are made in either inch-series with UNRF or UNRS threads, or metric with fine-pitch threads. They are secured by either square, hexagon or special domed track nuts.

 

Plow bolts are used to secure the cutting edges of earthmoving blades. They have a raised countersunk head with a square neck to prevent them from rotating during tensioning. Ajax plow bolts are forged from alloy steels and heat-treated to the specifications of the original equipment manufacturers. The minimum tensile strength is 170,000 lbf/in2.

Impact resistance is greatly improved by tempering and fatigue resistance reduced by having rolled threads. Plow bolts are made only in inch-series with UNRC threads and are secured with hexagon plow nuts.

 
Segment Bolts secure the sprocket segments in crawler equipment. Generally, segment bolts have a minimum tensile strength of 170,000 lbf/in2, although when metric is required, they are supplied as Property Class 11.9, depending upon the specifications of the original equipment manufacturer. In most cases, they have hexagon heads, but some special ā€˜Dā€™ heads are available if specified by the original equipment manufacturer.

 
Split - Link Bolts secure / join the linkages in crawler equipment. Generally, split - link bolts have a minimum tensile strength of 170,000 lbf/in2, although when metric is required, they are supplied as Property Class 11.9, depending upon the specifications of the original equipment manufacturer. In most cases, they have hexagon heads.
