Component Specifications

Definition
Clamping screws are threaded fasteners designed specifically for jaw assemblies in industrial machinery, providing adjustable and secure clamping force to hold workpieces or components in place during machining, assembly, or testing operations. These screws feature specialized thread profiles and head designs optimized for repeated clamping cycles and precise force application.
Working Principle
Clamping screws operate on the mechanical advantage principle of threaded fasteners, converting rotational torque into linear clamping force. When tightened, the screw thread engages with the jaw assembly's mating threads, creating axial force that compresses the jaw components against the workpiece. The screw's pitch and thread geometry determine the mechanical advantage and force amplification.
Materials
Typically manufactured from alloy steel (AISI 4140, 4340) or stainless steel (AISI 304, 316) with hardness ranging from 28-42 HRC. High-performance variants may use titanium alloys or precipitation-hardened stainless steels for specialized applications.
Technical Parameters
  • Head Style Hex socket, slotted, or knurled
  • Thread Type Metric (M6-M20), UNC/UNF, or ACME threads
  • Length Range 20-150 mm
  • Torque Rating 10-200 Nm depending on size
  • Surface Finish Black oxide, zinc plating, or passivation
  • Tensile Strength 800-1200 MPa
Standards
ISO 4762, DIN 912, ISO 898-1, DIN 933

Frequently Asked Questions

What is the difference between clamping screws and regular machine screws?

Clamping screws are specifically designed for repeated clamping applications with optimized thread profiles for better force distribution, often featuring finer threads and specialized head designs for torque application in confined spaces.

How often should clamping screws be inspected and replaced?

Regular inspection every 6-12 months is recommended, with replacement when thread wear exceeds 10% of original profile, corrosion is visible, or torque values deviate by more than 15% from specifications.

Can clamping screws be used with different jaw assembly materials?

Yes, but material compatibility must be considered. Steel screws work with most metals, while stainless steel or titanium screws are recommended for aluminum or composite jaw assemblies to prevent galvanic corrosion.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
