I am trying to order stronger lag bolts - can anyone confirm the exact size of the included lag bolts? 5/16" x 3.5"?

I used the supplied lag bolts and haven't had any issues. I'm 6ft and weigh 250lbs. I've been using this pull up bar daily, for the past 6 months. I love it.

I checked mine and the threads are indeed 1/4" x 20. I didn't measure the bolt part, but it appears to be in the 1.25 to 1.5" range length. which is all threaded, plus around half an inch for the rubber tip.

The total bolt length is 1-3/4" long (1-1/2" long from the bottom of the hex head to the end of threads) The diameter is 5/16 Hex head is 1/2" Hope this is of help to you. (They work great)

They are short, threaded, heavy hex head bolts and washers that screw in from the bottom. Not sure of the size, but I'd say appx 1/4" - 3/8ths" diameter maybe?

From Lowes I got this: The Hillman Group Construction Lag Screws 5/16 x 3-1/2Item #: 155913 | Model #: 47870I got 3 1/2 because I'm drilling them into a 4x6 beam. If you're not drilling into a wooden beam like this then use a slight variation.

Hello, No, they are the incorrect bolt pattern. You would want 5x4.75. Thanks, -Jon

Bolts were included and worked fine for my custom drilling with plenty of thread remaining. I do not know the exact measurements of the bolts unfortunately.

I purchased four lag bolts/screws at The Home Depot, and installed in the ceiling. I think they are 3 inches long.

We attached these to the molding on either side of our 9 foot garage doors. The lag bolts are 106 1/2 apart. There is an overhang of 3/4 inch on the inside of the molding. I tried to attach a picture but didn't know how.

Yes the box is pre-drilled for lag bolts you just have to make sure that you know the exact positioning before you put the bolts in, there is no room for adjustments. Also the python lock is recommended with this box with one of those locks that you cant cut with a bolt cutter... the round one. Good Luck.

I have found the lag bolts the kit came with to be a little narrow and long, but adequate for the job. If your feeling froggy it wouldn't hurt to get some a little wider with a coarse thread, and the appropriate length based on the thickness of your roof or structure.

The mount holes are 3/8 inch diameter. These hooks are the best I've seen ; they also come with 3/8 x 3 inch ss lag bolts.(the description doesn't say so but I ordered several sets of swing hooks and each one had lag bolts included) Hope this helps? Best of luck.

Yes, the normal size is 5/16 for the hanger bolt. But you can special order for the 10mm size, which is what I did. If you don't know, check your existing hanger bolt against a sizer at your local hardware store.

The 1/4x3 size lag bolt would definitely be strong enough with some caveats . . How solid is the material and the foundation into which they are being screwed? Hopefully you will be able to "hit" a rafter or other structural member supporting the outer roofing materials. Some composite shingle roofs are sheathed just using 1/2" plywood, so if that is all that the lag screw is going into not much is holding, and the length of 3" is just giving you a false sense of security. Second, the lag screw used should be "all thread" along its entire length. Some lag screw designs are "thread-less" for some distance along the shank next to the head. That design should definitely not be used in this application. Also, I would suggest using a flat washer (minimum 1" to 1-1/2" and known as a "fender" washer) between each lag screw head and the tripod leg mount hole. This will help to not deform the tripods' soft metal as the final tightening takes place and provide better distributed contact support. Use stainless steel washers for this to minimize future rust. . . One last thing . . After you figure out where each leg base will contact the roof for the support issue, squirt or put a dollop of roof-seal-compound under each between the mount and the roof, so that the lag being screwed in will actually carry sealant with it to insure a watertight seal. The excess that is compressed out in the process can be smeared around the immediate attachment point to complete a seal to your satisfaction. A throw-away 59 cent 1" plastic putty knife will be a valued investment! - I've been very satisfied with the mount used within the scope of its design. - - Hope this is in someway helpful . . Bob M.

Mine came with lag bolts and washers. Just need drill and wrench. Easy top install and very sturdy.

They are lag bolts I would say about 31/2 inch i belive I used a 3/8 for pilot hold and used a socket and my drill with hex bolt attachment to drive them in the stud they are very stout
