Replacement and magnetic rack pins
How to choose a replacement or magnetic rack pin: start from the maker's pin size, check usable shaft length, and read the pin maker's own limits and warranty.

Short answer
Start from the pin size your rack maker states, not the hole size. Match the diameter, check that the usable shaft is long enough to pass fully through, and read the pin maker's own limits. Buy the rack maker's replacement where one exists. Magnetic pins come with warnings from their own makers; follow them.
Start from the maker's pin size
The hole and the pin are two different numbers. Titan lists 11/16 in holes on the T-3,[2] and its support page states a 5/8 in pin size for its T-3 J-hooks (JHOOK_T3, SKU 401348).[3] Titan's T-3 accessory support page also lists a 5/8 in quick pin diameter.[3] If you shopped by the hole, you would look for the wrong size.
So look up the pin size first: in the rack maker's spec, its support pages or the manual for the attachment you are re-pinning. Our hole vs pin guide has more examples.
Diameter
Pin sizes are printed in inches or millimeters, and the two are not interchangeable:
| Label | Calculated |
|---|---|
| 5/8 in | 15.875 mm, slightly less than 16 mm[4] |
| 11/16 in | 17.4625 mm, about 1/16 in larger than 5/8 in[4] |
| 1 in | 25.4 mm[4] |
A pin labeled "16 mm" is not a 5/8 in pin, and a 5/8 in pin is not a match for every 11/16 in hole. Never swap in a thinner pin than the maker specifies.
Usable shaft length
The usable shaft length is the part of the pin that can sit inside the attachment and upright. Too short and it may not pass through both walls. Oak Club sells its MagPin 3 in pairs in 1 in and 5/8 in shaft sizes, with 4-1/2 in of usable shaft length and an aluminum head.[1] Compare that number with the pin it replaces, measured from under the head.
Oak Club does not publish magnet strength or a structural rating for the MagPin 3.
Retention
A replacement pin needs a way to stay put: a clip, a ring, a detent ball, a magnet or a knob. Match the retention the attachment maker designed for. If your attachment came with a hitch pin, a magnetic pin is a different lock, not a like-for-like swap. Our locking methods guide explains each type.
Warranty is shorter on pins
Pins wear and get lost, and makers cover them for less time than frames:
| Maker | Frames and structural welds | Pins |
|---|---|---|
| REP (US) | Lifetime | Pop-pins one year[5] |
| Bells of Steel (US) | Limited lifetime | 90 days[6] |
Both warranties apply to the original purchaser. If your rack is still under warranty, ask the maker for a replacement pin first.
Buy the rack maker's pin where one exists
A pin from your rack's maker is designed for its holes and attachments. Bells of Steel sells its own magnetic pins, one version per hole class:

Choose MAG-PIN-HDR (5.0 in shaft) for Bells of Steel Hydra racks with 5/8 in holes, or PIN-MAG-MTC (5.1 in shaft) for Manticore racks with 1 in holes.

Questions
What size pin does my rack take?
Use the pin size your rack maker states for its own attachments, not the hole size. Titan, for example, lists 11/16 in holes on the T-3 but a 5/8 in pin for its T-3 J-hooks.[2][3]
Are magnetic pins a good replacement for stock pins?
Only where the pin maker allows it. Oak Club says its MagPins are for experienced lifters only and tells users to check installation before each lift and always use a failsafe method of attachment securement.[1]
How long should a rack pin be?
Long enough to pass fully through the attachment and the upright as the maker designed. Compare the pin maker's usable shaft length with the pin it replaces; Oak Club lists 4-1/2 in of usable shaft on the MagPin 3.[1]
