Technical Guide: Custom Fastener Manufacturing Process

Overview

This comprehensive technical guide covers essential aspects of industrial fastener applications, providing practical guidance for engineers, procurement specialists, and maintenance teams based on LOKRON's two decades of experience.

Technical Requirements

Understanding applicable standards and specifications is crucial for proper material selection. Primary standards include relevant ASTM, ASME, EN, and ISO specifications.

Key Specifications

Specification	Scope	Key Requirement
ASTM/ASME	Material properties	Tensile, yield, hardness limits
EN Standards	European compliance	PED certification where applicable

Material Selection

Selection depends on operating temperature range, process fluid chemistry, mechanical loading, and environmental exposure.

Design Considerations

Proper design requires careful analysis of joint geometry, load distribution, thermal expansion, and long-term service conditions.

Installation and Quality Control

• Surface preparation and thread lubrication per ASME PCC-1
• Torque-tension relationship control using calibrated tools
• Multi-pass tightening sequences for uniform gasket compression
• Post-installation verification using ultrasonic or direct methods

LOKRON Supply Capability

LOKRON manufactures and supplies fasteners with complete material traceability (EN 10204 Type 3.1 certificates), PED certification where applicable, and custom engineering support.
