CAP NUT

The CAP NUT 152 525 68 (also indicated as 0277112814 and 152-525-68) is a high-strength protective CAP NUT engineered for Sandvik drilling rigs, ROC series equipment, and underground jumbos. The 152 525 68 CAP NUT secures threaded connections exposed to continuous shock loads, hydraulic oil, abrasive rock dust, and temperature fluctuation during mining and tunneling operations.

This 152 525 68 CAP NUT is manufactured from corrosion-resistant alloy steel with precision-formed threads and a closed-end design that shields fasteners from contamination and mechanical damage. OEM identifiers 0277112814 and 152-525-68 confirm full compatibility with Sandvik mechanical assemblies.

The 152 525 68 CAP NUT prevents thread wear, protects bolt ends, and maintains clamp load stability under severe vibration. It is critical in assemblies where exposed studs would otherwise corrode, deform, or collect debris that leads to maintenance difficulties and premature part failure.

Inspect the 152 525 68 CAP NUT for rounding, cracking, thread wear, or loss of torque retention. Replace 152 525 68 immediately if sealing capability or mechanical grip is compromised.
