Flange alignment hardware designed to make lining up pipe flanges quicker and more reliable. Flylin Two Hole Flange Alignment Pins combine precision machining with detachable threads and a built-in level for faster set-up on site. Are they the right addition to your toolbox or workshop?
⚡ At a Glance
- • Alignment Accuracy: Precision-machined threads and two-hole layout hold flanges concentric during bolting
- • Best for: Fitters and engineers aligning flanges on vehicles, ships and heavy machinery
- • Not ideal for: Applications requiring integrated hands-free torque tools or automated alignment rigs
Two-hole flange alignment pins with a 1-1/8 inch outer diameter and 2.75 inch length. Detachable threads adapt length and an 02-type option includes a built-in level for quicker checks.
Accurate flange alignment - with precision-machined threads and two-hole layout
Precisely machined threads line up with flange bolt holes, while the two-pin arrangement prevents rotation and holds faces concentric. The machining tolerance ensures a snug fit between screw and bolt during assembly.
Securely holds flanges in position for safe, repeatable bolting, reducing the need for rework and helping avoid leaks.
Quicker, level installations - with a built-in level on the 02 type
An integrated bubble level in the 02 variant gives a direct visual reference for flange orientation, removing the need to fetch a separate spirit level. The level sits within the pin body for immediate checks during placement.
Speeds up set-up and makes it easier to achieve a correct flange orientation, particularly useful in confined or awkward workspaces.
Adjustable fit across jobs - thanks to detachable threads and compact size
Detachable threads allow the effective pin length to be varied to suit different flange gaps, while the 1-1/8 inch diameter and 2.75 inch nominal length suit a wide range of flange sizes. The simple, detachable construction keeps installation straightforward.
One set adapts to multiple pipe and flange combinations, reducing the need to carry several dedicated spacers or pins.
✨ The 4 Key Reasons for Flylin Two Hole Flange Alignment Pins
- Built-in level (02 type) - cuts set-up time with immediate visual levelling checks
- Detachable threads - adapt pin length quickly for varying flange gaps
- Lightweight aluminium construction - easy to carry between jobs and low user fatigue
- Wide flange compatibility - works across Class 150 and Class 300 flange ranges

❓ Frequently Asked Questions
Q: What flange sizes do the pins fit?
A: They fit flanges from 1/2" pipe to 12" for Class 150, and 1/2" to 8" for Class 300, with compatibility for 2" thick flanges.
Q: Does the set include a level?
A: The 02 type includes a built-in level, allowing quick visual checks during alignment; other types do not include the level.
Q: Are the pins adjustable for different flange gaps?
A: Yes, detachable threads let the effective pin length be adapted to different flange gaps, simplifying installation.
🏆 Our Verdict
The pins suit fitters, shipyard technicians and workshop engineers who frequently align pipe flanges across varied sizes. Precision machining, detachable threads and an optional built-in level make the set a practical, time-saving tool. While initial choice will depend on specific site needs, durable aluminium construction and multi-size compatibility point to good long-term value.
