5P8136

The 5P8136 is a 1" countersunk plow bolt with 1"-8UNC threading — one of the essential fasteners in ground engaging equipment. At 102 mm (4") overall length, this Grade 10.9 fastener is manufactured by AzuLong Wear Parts from 40Cr Alloy Steel with black oxide finish. Used to mount cutting edges, wear plates, and ground engaging tools on Caterpillar ground engaging equipment including motor grader blades, wheel loader cutting edges, bulldozer end bits, and scraper cutting edges.

Grade 10.9 — Strength & Performance

Grade 10.9 (Class 10.9) plow bolts provide a tensile strength of approximately 1040 MPa and yield strength of 940 MPa. The higher strength rating makes these bolts essential for heavy-duty cutting edge and ground engaging equipment where bolts must resist shearing forces from rock and compacted material. Manufactured from 40Cr alloy steel with controlled heat treatment to achieve consistent mechanical properties.

1" Diameter — Size & Application

The 1" diameter plow bolt is designed for heavy-duty applications including large bulldozer cutting edges, mining shovel lips, and heavy grader blades. The substantial cross-section provides maximum shear resistance for the most demanding ground engaging conditions.

Equipment Compatibility

This plow bolt is used across: CAT Motor Graders (120, 140, 160), CAT Wheel Loaders (950, 966, 980), CAT Bulldozers (D6, D7, D8), CAT Scrapers (613, 621, 631). The countersunk head design allows the bolt to sit flush with the cutting edge surface, preventing the bolt head from protruding into the material flow path where it would cause accelerated wear and reduced cutting efficiency.
