Component Specifications

Definition
A latch bolt is a cylindrical or rectangular bolt component that extends from a latch mechanism to engage with a corresponding strike plate, creating a secure closure. It operates through manual, spring-loaded, or electromechanical actuation and is designed to withstand operational forces while maintaining alignment and durability in industrial environments.
Working Principle
The latch bolt operates by extending or retracting through linear motion, typically driven by a handle, lever, or actuator. When extended, it engages with a strike plate, preventing unintended opening. Retraction disengages the bolt, allowing access. Spring mechanisms often provide automatic return to the locked position, while deadbolts require manual operation for added security.
Materials
Commonly made from carbon steel (e.g., AISI 1018, 1045), stainless steel (e.g., AISI 304, 316), or zinc alloys. Surface treatments include zinc plating, powder coating, or passivation for corrosion resistance.
Technical Parameters
  • Throw 10-25 mm
  • Length 20-100 mm
  • Diameter 8-20 mm
  • Load Capacity 500-2000 N
  • Operating Temperature -20°C to 80°C
Standards
ISO 9001, DIN 18257

Frequently Asked Questions

What is the difference between a latch bolt and a deadbolt?

A latch bolt is typically spring-loaded and retracts automatically when the handle is turned, while a deadbolt requires manual key or knob operation and lacks a spring mechanism, offering higher security.

How do I select the right latch bolt for an industrial application?

Consider factors like material compatibility (e.g., corrosion resistance), load capacity, throw length, operating environment (temperature, humidity), and compliance with industry standards such as ISO or DIN.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
