Description
M24 joints with a 36 mm hex hold press columns, gearbox feet and large pump bases. Many sit on long studs or behind heavy pipe, where a socket cannot go. The Snap-on QZOM36ADP open end head solves that on a Z-shank (0.990 in) body. Its dual-pin shank locks into the body for heavy pulls.
36 mm hardware the QZOM36ADP fits
- ISO 4032 and DIN 934 M24 nuts, which both use 36 mm.
- 22L and 20S tube nuts under ISO 8434-1, found on large hydraulic lines.
- Lock nuts on big threaded rods and tie bars, where only side access exists.
Older or special parts can differ, so measure the flats before you order.
The long Z body behind the Snap-on QZOM36ADP open end head
For Z work, CAT1500i offers one dual-range body, the QD4IN800A. It reads 150 to 800 N·m, or 129 to 572 ft-lb, and its table carries a note about dual-pin heads. However, the body measures 41-1/2 in and weighs 11.14 lb. So plan for a two-hand pull, a firm stance and clear floor space behind the joint.
Head limit: ask before you set the QZOM36ADP
Snap-on’s two books print different maximum working torques at 36 mm. Also, the UK brochure lists a single-pin QZOM36A rather than this DP part. Therefore we leave the rating out, and Lost in HCM confirms it with the quote. Whatever the figure, keep the QD4IN800A below it, even though the scale reads higher.
Clearance around a 74 mm jaw
The Snap-on QZOM36ADP open end head measures 74 mm across and 15 mm deep, and both books agree. As a result, it needs about twice the hex width to swing freely. Check that a nearby flange or guard leaves that room. If not, a 12-point ring may fit better when you can reach over the nut. For example, the UK brochure lists the QZXM36A box end head at only 53 mm across.
Quote steps for the Snap-on QZOM36ADP open end head
SMK Vietnam lists this jaw, while Lost in HCM supplies it and issues the quote. Request a quote from Lost in HCM and say whether you already own a Z body. If not, ask for one on the same quote. The full head range sits under torque wrench heads and adaptors, and you can contact SMK Vietnam about large-joint setups.
M24 and 36 mm FAQ: QZOM36ADP
Is there a lighter 36 mm open end head?
Yes. CAT1500i lists 36 mm jaws for the J, Y and X shanks too. Choose one of those when the M24 spec is low and your body is lighter.
Is the QD4IN800A fine for loosening a rusted 36 mm nut?
No. Snap-on’s catalog warns against using its torque bodies to crack fasteners free. Free the nut with a striking wrench first, then torque it with the QZOM36ADP.
Why does the brochure show QZOM36A instead?
The UK brochure lists a single-pin part number at 36 mm. This page covers the dual-pin QZOM36ADP from CAT1500i, so quote that exact number.
