Sep 30, 2020 · For example, an eye bolt with a 1/4 inch shank can typically hold up to 600 pounds at a straight pull (no angle). However, at a 15 degree angle, the maximum weight capacity drops to 480 pounds (80% of the “straight pull” weight capacity).

Forged Eye Bolt Capacity and Strength Chart to show rated load capacities, proof load and breaking strength of a selected forged threaded eye bolt. The chart is according to ASME B18.15 and ASTM A 489 - 04 standards.

Working load limits for eye bolts are based on a straight vertical lift in a gradually increasing manner. Load limits are based on a safety factor of 5 to 1. Angular lifts will significantly lower working load limits and should be avoided whenever possible.

Plain Eyebolts must have full thread shank engagement, allowing for one-half turn for proper eye-alignment to obtain rated capacities.

Sep 14, 2023 · We recommend checking for a ¼-20, which can hold a more reasonable 500 lbs. TIP: Check out our full chart below to find all sizes, dimensions and weight limits for eye bolts. After taking a look at eye bolt sizes, you might want to …

ASTM A489 Impact Strength. The lifting eyes shall have an average Charpy V-notch impact strength of not less than 35 ft·lbf (47 J) at 0°C (32°F). The impact strength shall be the average of three specimens tested.

Apr 27, 2023 · The threaded portion varies for each eye bolt, so visit our website if you need more detailed dimensions of our eye bolts. Strength and Durability from Different Manufacturing Methods An indicator for how strong or durable an eye bolt will be is the way it is manufactured.

Meets or exceeds all requirements of ASME B30.26 including identification, ductility, design factor, proof load and temperature requirements. Importantly, these bolts meet other critical performance requirements including fatigue life, impact properties and material traceability, not addressed by ASME B30.26. Weight Per 100 (lbs.)

BoltPort can manufacture lifiting eye bolts as per ASTM A489 and supply with EN 10204 type 3.1 certification. ASTM A489 Breaking Strength and Proof Load Requirement, Types 1 & 2. Where As = Stress area, in 2, D = Nominal bolt size, and n = Threads per inch.

Working load limits for eye bolts are based on a straight vertical lift in a gradually increasing manner. Standard forged eye bolts should not be used with angular lifts. If an angular lift is required, a properly seated shoulder pattern machinery eye bolt must be used.
