Clamping Handle Screw (Short) — DIN 6336 / GN 313 (Series 042) are used primarily for structural and machine joints that must be tightened to a controlled preload. This page summarizes where they fit, the industries that rely on them, and the practical points to get right when you specify them — to DIN 6336 / GN 313. Stocked across roughly M5 to M12, they cover general to heavy-duty work.
Typical Applications for Clamping Handle Screw (Short) — DIN 6336 / GN 313 (Series 042)
The most common settings where these are specified:
- Energy & infrastructure: tower, pylon and pipework supports exposed to weather and long service life.
- General machine building: fastening covers, brackets, motors and sub-assemblies on production equipment.
- Maintenance & repair (MRO): a stocked size for servicing existing plant where the original fastener spec must be matched.
- Fabrication & metalwork: bench and on-site assembly of steel frames, enclosures and weldments.
- Structural steel: bolting beams, base plates and bracing where a defined preload and property class are required.
How to Specify Clamping Handle Screw (Short) — DIN 6336 / GN 313 (Series 042) for Your Application
- Size: Match the nominal size to the mating thread or hole. This product spans M5–M12; check the full table below for the exact dimensions of each size.
- Strength class: Choose the property class (e.g. 8.8, 10.9, 12.9 or A2/A4 stainless) for the load and environment, and tighten to the matching torque so the joint relies on preload, not friction.
- Environment: For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
- Standard: This product is supplied to DIN 6336 / GN 313. Quoting the standard on your order guarantees interchangeable dimensions between suppliers.
Where Clamping Handle Screw (Short) — DIN 6336 / GN 313 (Series 042) Are Not the Right Choice
Not for permanent joints that will never be opened (a rivet or weld is cheaper), and not where the head must sit flush — use a countersunk screw instead.
