An eyebolt, also known as a lifting eye or eyelet, is a bolt with a loop at one end. The eye bolt has a threaded shank or rod which is securely screwed into a structure. Once the bolt is secured in place, ropes or cables can be anchored to or fed through the protruding loop. Heavy-duty eyebolts can be used in rigging for lifting heavy loads, smaller eyebolts can be used for tensioning wires, securing loads and in other non-load bearing applications.

Types of Eyebolt
Forged: These eyebolts are forged as one piece rather than formed and have a continuous eye and shoulder. This design enables them to be used for heavier loads.
Plain or Regular: These eyebolts are used for vertical loading only and are not recommended for angular lifting. They can also be used with tie downs to secure loads and as wire guides
Collared: Collared or shouldered eyebolts are fully threaded and reinforced with a collar or shoulder. When installed the shoulder sits flush with the mounted surface and offers more stability to the base of the eye and prevents bending and deforming. This design means that these eyebolts can be used for angular loads of up to 45°.
Commercial or Load Rated: These eyebolts are designed for use in lightweight non-load bearing applications such as securing ropes or cables to posts and are not used to lift or suspend an object. Load rated eye bolts often have embossed stamping on the body of the eye bolt stating the working load limit (WLL), batch number and thread size.
Machinery: Machinery eye bolts are forged and shouldered and have threads with a high holding strength. These eyebolts have a heavy-duty design and are made to high specifications and standards. Applications include connection points in rigging applications and, due to their shouldered design, can be used to angled loads

Our lifting eye bolts correspond to standard sheet DIN 580.

The following guideline of lifting eye bolts DIN 580 the have to be observed in addition to the load values given in the datasheets.

The eye bolt must be of fully screwed in to achieve a perfect contact between the two mating faces.

Product TypeWeld Stud
GradeAISI 304
MaterialStainless Steel
ThreadedYes
ConditionNew

CD Studs, or Capacitor Discharge Weld Studs, are mainly used in sheet metal applications. Where a fabricator may drill a hole to insert a bolt for an attachment point, a CD Stud can be shot to the attachment side with no reverse side marking or bolt head. This leaves a clean and well finished look to the product with no compromise in quality or strength and achieves a significant time and cost savings.
CD (capacitor discharge) stud welders utilize a capacitor storage system to produce a rapid electrical discharge, resulting in fast, high-integrity welds, even on thin-gauge materials. In contrast to arc welds, CD welds do not require ceramic ferrules or gas. The direct-current arc creates a shorter weld time, renders oxidation and heat concentration provided by ferrules and fluxes unnecessary.

These are suitable for use with Stud Welding Machines.
Our range of CD Weld Studs are as per DIN 32501/3 or ISO 13918.

M3 to M8 upto 50mm length
