Product Overview

DIN 444 swing bolts are designed for applications where the fastener needs to pivot around a pin or shaft while providing adjustable threaded clamping.

The closed eye allows the bolt to remain connected to the assembly during opening, adjustment or maintenance, making this design useful in machinery covers, fixtures, molds and hinged equipment components.

VALTOR supplies swing bolts in stainless steel and carbon steel materials with different thread sizes, eye diameters, shank lengths and surface finishes.

Custom dimensions can be produced according to drawings, samples or specific equipment requirements.

Pivoting & Clamping Solutions

Swing bolts are selected for assemblies that require both pivoting movement and adjustable threaded clamping.

1Eye & Pivot Design — The closed circular eye connects to a pin or shaft, allowing the bolt to pivot while remaining attached to the assembly.
2Threaded Clamping Adjustment — The threaded end allows clamping force and position to be adjusted using a compatible nut or hand-tightening component.
3Custom Dimensions — Eye diameter, shank length, thread size and overall length can be customized according to machinery drawings or samples.

Frequently Asked Questions

What are DIN 444 swing bolts used for?

DIN 444 swing bolts are commonly used in machinery, clamps, fixtures and hinged assemblies where the bolt needs to pivot around a pin while providing adjustable threaded fastening.

What is the difference between a swing bolt and a lifting eye bolt?

A swing bolt is designed for pivoting and clamping in mechanical assemblies. A lifting eye bolt is designed for lifting or rigging loads. They should not be treated as the same product.

What materials are available for swing bolts?

Common options include 304 stainless steel, 316 stainless steel and carbon steel, depending on corrosion resistance and application requirements.

Can the eye diameter and bolt length be customized?

Yes. Eye dimensions, shank length, thread size and overall length can be produced according to drawings, samples or project requirements.

Can you supply DIN 444 swing bolts with different surface finishes?

Yes. Stainless steel can be supplied plain or passivated, while carbon steel options can include zinc plated, black oxide or plain finishes.
