What Are Square Head Track Bolts and Why Use Them?
Square head track bolts, also called plow-style, feature flat shoulders that prevent spinning during high-torque installs. They excel on track shoes for dozers and excavators in abrasive conditions like Alberta oil sands, offering higher shear strength and reduced snagging on terrain. AFT Parts supplies OEM-spec square head bolts compatible with CAT and Komatsu models.
What Makes Hex Head Track Bolts Different for Undercarriage?
Hex head track bolts have six-sided heads for quick wrenching, ideal for lighter loads and confined access on mini-excavators. They simplify field repairs with standard torque specs and are suited to smaller sizes. AFT Parts offers precision hex bolts compatible with Kubota and Bobcat, backed by 12-month pro-rated warranty for Ontario and Quebec shops.
