Hexagonal Screw 100412

Hexagonal Screw 100412 for Gas Engines

Function & Role:

The Hexagonal Screw 100412 is a critical high-strength fastener in gas engines. Its primary role is to securely join major components, such as cylinder heads, manifolds, or critical covers, ensuring structural integrity and maintaining a tight seal under extreme pressures and temperatures. It directly contributes to engine reliability, preventing leaks and maintaining optimal compression.

Usage & Method:

Installation: It must be installed into a pre-tapped hole using a calibrated torque wrench and a proper hex key/socket.

Torque Procedure: Strict adherence to Jenbacher's specific torque specification and sequence (often a multi-stage angular torque method) is mandatory. This ensures even clamping force.

Preparation: Threads must be clean, undamaged, and typically lubricated with an approved anti-seize compound as specified in the engine manual.

Replacement: Reuse is generally not recommended. It should be replaced with a new screw during major overhauls or as per maintenance schedules.

Key Features:

High-Grade Material: Made from heat-treated alloy steel for high tensile strength and fatigue resistance.

Precision Thread: Ensures perfect engagement and reliable clamping force.

Hexagonal Drive: Allows for high-torque application and secure gripping.

Corrosion Resistance: Often coated to withstand the engine's harsh operating environment.

In summary, Screw 100412 is a precision component whose correct installation and replacement are vital for the safe, leak-free, and durable operation of Jenbacher engines. Always consult the official engine manual for the exact procedural specifications.
