Part Number: 805639371
The 805639371 Fastening Pin is a precision-machined iron component designed for the rugged structural demands of Down-The-Hole (DTH) drilling rigs. Operating as a critical securing mechanism, this durable hardware ensures that structural joints, linkages, and moving assemblies remain firmly locked in place during high-vibration drilling cycles. By maintaining tight dimensional tolerances, it prevents joint play and structural fatigue, acting as an essential safeguard for the mechanical integrity of your heavy-duty mining equipment.
Precision Machined: Manufactured to exact dimensional tolerances to ensure a snug, secure fit within mounting brackets and linkages, eliminating dangerous mechanical play and vibration wear.
High Shear Strength: Machined from high-strength iron to reliably resist the extreme shearing forces and constant structural stress inherent to percussive rock drilling.
Compact & Low Profile: Weighing just 0.07 kg (with compact packaging of 20 x 15 x 2 cm), it provides massive securing strength without adding unnecessary weight to the rig's chassis or mast assemblies.
Vibration Resistant: Specifically designed to maintain a locked, steadfast position even under the severe, high-frequency impact cycles typical of DTH blasting operations.
The primary function of the 805639371 Pin is securing and fastening critical pivot points, mast joints, structural hinges, or cylinder linkages on DTH drilling rigs. It ensures that mechanical sub-assemblies operate safely as a rigid, unified structure. Reliable fastening prevents the misalignment of drifters and feed beams, which is crucial for straight-hole drilling and protecting adjacent structural welds and mining equipment seals from unnatural torque and stress.
Primary Application: Down-The-Hole (DTH) Drilling Rigs / Surface Blast Hole Drills.
Note: Please verify part number 805639371 with your equipment's parts catalog to ensure exact pin diameter and length compatibility prior to ordering.
