what is the weight bear load on this bolt in the largest size (thread length 2-1/2inches)?
They technically don't rate the wood screws for load bearing, because they are unable to rate the interface between the threads and the wood. Pine would be different from Walnut or Oak, etc.It seems reasonable to take the load ratings from their identically-sized machine screws and apply to these, with the understanding that the rating only applies to breakage of the screw and not to it potentially pulling out from the wood it's screwed into. Disclaimer: I am not a structural or mechanical engineer and have no ability to guarantee the structural integrity of anything whatsoever.So, if you're looking at the 2.5-inch size of the 3/8" (diameter) screw, the corresponding rating would be 1,200 pounds at a safety factor of 5:1. If the load is pulling at an angle (rather than straight out, parallel to the screw), you may need to derate it by up to 90%.If you're using a different size, find the same-sized Chicago Hardware machine screw. Find the size screw you're looking at, then find the corresponding (same-sized) machine-thread version, which will have a load rating. But keep in mind, again, that this rating does not apply to the interface with the wood, and must be derated if the screw is used at an angle.Really, the short version of this answer is: wood screws don't have load bearing ratings.Best of luck!
I have no idea. You would have to ask the manufacturer, and I suspect they will not tell you because that would depend heavily on what it is screwed into. If it was screwed into a piece of solid oak it would hold a lot more than normal pine/fir framing. And it would also depend on how carefully you drilled the pilot hole. And it also depends on the direction of pull. But it is still just a fancy lag screw, not a through bolt with a nut and washer on the other end. My gut says don't put much more than 50 pounds on it, but don't quote me on that. I'm using mine to hold a rope that goes to the corner of an outdoor sunshade/awning, and I suspect the load is only about 15-20 pounds max with a spring in the line to absorb shock loads, and mine is screwed into a piece of white oak that is the lifting beam at the peak of a small barn. Also be aware that my German family motto for building things is "Hell fur strong" Besten Gluck! (Good luck!)
Sorry, i done know.The answer varies based on the application, material it is fastened to and the angle at which tension is applied.
I am curious about why Jamestown thinks that a customer can answer a question about the technical specification of their product. I am unable to answer your question. The manufacturer's data sheet should provide your answer.
I don't have any of knowing. I only have about 75lb on them but the force is not straight down - more sideways. I would look on the internet for load bearing capacity for a bolt 5/8" diameter/2-1/2" thread length. I would bet there is something there.
Which thread type using for Shoulder Screw Eye Bolts? (Example: G-275 Screw Eye Bolt)
We used the lag screw thread in this instance because the backside of the timber we were installing it on was not accessible. My first choice for eye bolts is always a machine thread, through drilled with a backer washer or plate and nut. In this case it was not possible, and loading was not a factor.
Don't quite understand what you are looking for, but the tread type is what you see in the display, G-275 For direct fastening to mostly wood constructions. Obviously, nuts or washers are not needed, these are not machine eye bolts. Sorry, but I don't understand your question? WYSIWYG.....
Sorry that I can't be of much help since this piece of hardware was installed by a local handyman with whom I no longer have contact. It was purchased for the purpose of holding a boxing heavy bag, not for any boating use.
I plan to screw this into a 4 x 4 and hang a loft from the ceiling (one corner only) I think the total weight will be less than 500 lbs, will this work ??
Olie,I would look to use a through bolt, drilled and secured with washer, lock washer and nut, to depend on the threads to hold your loft seems to ask a lot from the screw. just a thought.
Yes it will. I assume 4 bolts will be used. Be sure to properly pre drill all holes of course.
Maybe. I'm quite certain the lag screw itself can handle that amount of weight but the most pressing issue is how it is screwed in and the direction of the weight involved. Mine are used at a right angle to the threads.
what weight can it hold? use would be for anchoring a swing to a joist

What drill bit size should I use for these (in a masonry wall)?
Unfortunately I put these into white oak so will not be able to comment on masonry wall.....Sorry
I have only used them in wood.
I wouldn't try and use a lag "screw" in masonry. Screws are meant for use in material that will deform (wood metal plastic etc.) I think the masonry will crack or crumble. Most masonry fasteners are meant to wedge.Just my humble opinion, I would look for something else.
how many is in a box ?
I just bought two seperately (no box).Good quality, happy with them.
The price is per each. Yikes, these seem expensive but they are more trustworthy than the kind of bolt that is merely bent into a circle. I pre-drill into the center of the overhead beam and epoxy (West brand) them in... very secure.
We only bought four loose eyebolts - they weren't in a box.Graham (not Roger!)

1st time experience dealing with JD..... Great job !
Struggling to find the right part. After several attempts with others, found Jamestown distributors.1 quick phone call, and the order was quickly placed. Item shipped and received ahead of expectations. Great experience..!
Master of none.
Exactly what I needed!
Great bonus, these are made in the USA! I use them to hoist 8 foot logs (for firewood) into my truck with a hoist. MUCH more secure than a sling.
Great shoulder eye bolt
Used these eye bolts on each side of door frame inside to slide a steel pipe through to prevent the doors from being busted through during a home invasion attempt.
Bicycle anchor in concrete floor
These eye bolts are excellent for securing bicycles to a concrete floor. Just drill a 1/2" x 3" hole in the carport floor with a carbide drill, fill it with quick setting anchoring cement, insert the threaded end into the hole and let it set for a day before use.This sturdy anchor will not come loose and cannot be cut, but be sure to get a heavy duty chain and padlock for the bicycle or scooter.I have used these eyebolts for anchoring bicycles in an open carport in my apartment building.
These Eye bolts are awesome
These are massive eye bolts and perfect for my project of cabling down an expensive grill outside our office building. After locating 5/8" lag shields, I installed these and required a tire iron to finish screwing them in. Nuclear attack won't loosen these. They are much better than the bent-wire eye bolts that consumer hardware stores sell which can be un-bent quite easily.
Great for Stall Guards
Have used these for years to as the eyebolts for stall guards (for horses, in case you are wondering). Very strong, don't work open like the cheap formed eyebolts-- the deformed open cheap eyebolts can form a hook and can cause serious injury. Was worried that perhaps these galvanized eye bolts would shatter and leave a sharp edge, but never has happened (CHI-08920-3 half inch by 3 with 1 inch eye).
I've been looking everywhere for these!
These are perfect for securing a bicycle to a sill joist. Common eyebolts can easily be pried open. Very rugged constrction.
