B311-5-Y Toggle latch clamp — spring-loaded, hook, horizontal base (Kukamet)

The B311-5-Y is a spring-loaded toggle latch clamp designed for secure and repeatable fastening in jigs, fixtures and small production tooling where quick engagement and a compact footprint are required.

• Spring-loaded toggle action for reliable closure
• Horizontal-foot mounting for stable bench fixing
• Hook connection with adjustable arm 51.5–81.5 mm
• Holding force 725 N and clamping force 500 N

Secure, repeatable clamping for production tasks

The robust toggle mechanism provides a predictable clamping force and holding force, specified at 500 N and 725 N respectively, which translates into consistent part retention during machining, assembly or inspection cycles. In practical terms, clamping force denotes the pressure applied to the workpiece to perform secure fixing, while holding force describes the maximum resistance to separation once the clamp is engaged. This differentiation helps planners select a closure that meets both static and dynamic process requirements without over‑specifying hardware.

Fast installation and straightforward adjustment to save setup time

Equipped with a horizontal foot for bench or platen mounting and an adjustable arm ranging from 51.5 mm to 81.5 mm, the clamp offers simple alignment and repeatable positioning in fixtures. The 110 mm thread length permits fine tuning of the hook engagement, enabling quick setup changes between different workpiece heights. Because of its compact mass (approx. 0.98 kg), integration into mobile jigs or modular tooling is uncomplicated, reducing overall changeover time and improving line efficiency.

Durable mechanism with a spring for secure engagement

The unit’s spring-loaded feature ensures positive engagement under vibration or intermittent loads: the spring maintains preload on the hook so that the latch stays engaged until deliberately released. The component carries a blackened finish, which provides a uniform appearance and surface protection suited to workshop environments. The combination of a simple mechanical design and the spring retention reduces maintenance intervals and offers straightforward replacement of wear parts where necessary.

Versatile applications across workshop and light industrial use

As a compact lever-style clamp, this model suits repetitive clamping tasks in small-batch production, assembly stations and test rigs where rapid manual operation and dependable closure are priorities. The hook connection supports secure retention of irregular parts or removable fixtures, while the horizontal mounting keeps the actuator accessible without occupying excessive vertical space. Its characteristics make it well suited to both mechanical workshops and light industrial production lines seeking reliable, repeatable clamping.

FAQ

What is the difference between clamping force and holding force?
Clamping force refers to the pressure the clamp applies to the workpiece (500 N for this model), while holding force is the maximum resistance to separation once engaged (725 N for the B311-5-Y toggle latch clamp).

Can the arm length be adjusted for different workpiece heights?
Yes, the clamp features an adjustable arm from 51.5 mm to 81.5 mm and a 110 mm thread length to fine-tune engagement for varying part heights.

Is the latch suitable for use on assembly jigs with repeated manual operation?
The spring-loaded design of the B311-5-Y ensures positive engagement and quick manual operation, making it suitable for repetitive tasks in assembly and fixturing.

What mounting arrangement does this clamp require?
The unit uses a horizontal foot mounting configuration, designed to be fixed to benches, plates or tooling bases where lateral access and compact installation are needed.
