Steel Stepped Collared Flange Nut for Precision Locating

Product Content:

Our cold-form presses turn out these Steel Stepped Collared Flange Nut for Precision Locating by the thousands from Qimao Metal Manufacturer. The collar indexes into the bore—that’s your locating feature. The flange gives you a wide bearing surface so clamp pressure spreads evenly without marking up your fixture plates. We use heat-treated carbon steel, black oxide coated, with rolled threads that torque up smooth and consistent. The collar and thread are held concentric within a few thou, so what you clamp stays where you put it. These go into automotive fixture setups, machine tool workholding, and modular jig systems where repeatability matters. No fancy sales pitch—just a solid nut that does what it’s supposed to, shift after shift.

Technical Details:

The Steel Stepped Collared Flange Nut for Precision Locating OD, the flange diameter, and the thread class. We hold the collar to a tight tolerance so it slides into standard locating bores without slop, but doesn’t need a hammer to seat. The flange is machined flat and square to the thread axis—if it’s off by even a few thou, your clamped part sits crooked. Threads are rolled, not cut, because rolled threads have better grain flow and fatigue resistance. Surface is black oxide, which gives some corrosion protection and holds oil. No plating that flakes off. We also offer phosphate if you need more aggressive rust resistance. Sizes range from M6 up to M24, and inch equivalents from 1/4″ to 1″. All of them are marked with the grade on the flange face so your guys can identify them later.

Core Advantages:

• Steel Stepped Collared Flange Nut for Precision Locating collar registers into the bore for true position locating

• Wide flange eliminates the need for a separate washer in most setups

• One-piece steel construction—nothing to come loose or misalign

• Black oxide finish sheds oil and resists surface rust in normal shop conditions

• Rolled threads give consistent torque readings and better fatigue life

Wide Usage:

• Steel Stepped Collared Flange Nut for Precision Locating modular fixture plates and subplates where hole locations repeat

• Jig and workholding setups that need quick changeovers without losing position

• Machine tool accessory mounting (like vises or rotary tables)

• Die and mold base assembly where dowel pins aren’t practical

• Automotive powertrain fixtures that see high clamp loads in production
