Locking Fastener Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

A precision-engineered locking fastener used in syringe holder/clamp assemblies to prevent unintended movement or loosening during operation. It employs mechanical locking mechanisms to maintain consistent clamping force and positional accuracy, ensuring reliable performance in automated fluid handling systems.

Working Principle

Utilizes thread deformation, nylon inserts, or chemical adhesives to create resistance against vibrational loosening. Some designs incorporate prevailing torque features or secondary locking elements that engage when fully tightened.

Materials

Stainless steel (AISI 304/316), alloy steel with corrosion-resistant coatings, or engineered polymers for specific applications.

Technical Parameters

Thread Size M3-M8
Torque Range 0.5-10 Nm
Locking Torque 20-30% above standard fasteners
Temperature Range -40°C to 200°C
Vibration Resistance Meets DIN 25201 standards

Standards

ISO 898-1, DIN 6921, ISO 16047
