15069388 Locking Screw for Sandvik Rock Drilling Equipment

Part No: 150 693 88

The 15069388 locking screw is a precision fastening component engineered for use in Sandvik rock drilling and heavy-duty mining equipment. Its primary function is to secure critical mechanical assemblies under extreme vibration, cyclic loading, and continuous operational stress.

In drilling systems where stability and alignment are non-negotiable, this locking component ensures that structural and functional parts remain firmly fixed throughout long working cycles. Designed for harsh environments, it contributes directly to equipment reliability, operational safety, and reduced maintenance frequency.

This component is supplied worldwide by 3GEN Export as an OEM-standard solution, with global delivery in 5 working days.

Function and Purpose

This locking fastener is designed to prevent unwanted movement in assemblies exposed to high torque and vibration. Unlike conventional screws, it is manufactured specifically for demanding drilling applications where loosening can cause severe mechanical failure.

Key functions include:

• Securing internal and external assemblies

• Maintaining precise alignment of components

• Preventing vibration-induced loosening

• Supporting long-term mechanical stability

The 150 693 88 locking screw plays a critical role in protecting surrounding components from secondary damage caused by micro-movements.

Material Quality and Manufacturing

Manufactured from high-grade alloy steel, this fastening element undergoes controlled heat treatment to achieve superior strength and fatigue resistance. The balance between hardness and elasticity allows it to withstand shock loads without cracking or deforming.

Manufacturing advantages include:

• High tensile and shear strength

• Excellent resistance to thread wear

• Stable performance under temperature fluctuations

• Long operational lifespan in abrasive environments

Surface finishing improves corrosion resistance and ensures consistent torque application during installation.

Design Characteristics

The design of this locking component is optimized for precision and durability. Thread geometry is carefully machined to distribute load evenly, reducing stress concentration and improving holding power.

Design highlights:

• Precision-cut metric threading

• Controlled shank geometry

• Optimized head design for torque transfer

• Reduced risk of galling or seizure

These features simplify installation and enhance reliability during extended service intervals.

Application Areas

This locking screw is commonly used in Sandvik rock drilling and mining systems where secure fastening is essential. Typical applications include:

• Drifter assemblies

• Rock drill units

• Rotary and percussion mechanisms

• Structural fastening points within drilling rigs

Its performance consistency makes it suitable for both surface and underground operations.
