Product Description

Product Grade

Shoulder Type Eye bolt grades for the fastener are defined by strength and material standards, critical for safe lifting. Common grades include 4.8, 8.8, 10.9, and 12.9 for carbon steel variants—higher numbers mean greater tensile strength. Grade 4.8 suits light-duty tasks like home DIY, while 8.8 works for general industrial use. High-strength 10.9 and 12.9 grades handle heavy loads in construction or machinery.

Stainless steel versions often follow A4 (316) or A2 (304) grades, prioritizing corrosion resistance for marine/chemical environments. Forged alloy steel grades offer superior durability for extreme lifting. Each grade is marked with load ratings, ensuring compatibility with intended applications and safety compliance.

Product quality control

Quality control for an Shoulder Type Eye bolt means doing thorough checks to make sure it’s safe and works right. This process usually involves making sure the material grade is correct, checking the threads to see if they’re accurate, and running load tests to confirm the Working Load Limit (WLL). They also check if the dimensions match standards like DIN or ISO. Every batch of Eye bolts should be traceable, and you’ll get a certification to prove it meets the requirements for how you’re gonna use it.

Q&A Session

Question: How should I correctly install an Shoulder Type Eye bolt?For a standard bolt, screw it all the way in straight into a tapped hole—make sure the eye shoulder touches the surface. Pulling at an angle will totally cut down its safe working load, and that’s dangerous.
