DIN 912

DIN 912 with nylon thread locking treatment

A cylindrical head with a hexagon socket allows operation with a hex key. Connection design or repair must provide head clearance and tool access from the socket side. Pre-applied thread treatment is an additional specification independent of DIN 912 screw geometry.

Variant 267-28 KLF

Go to the group for pre-applied nylon treatment 267-28 KLF. Nylon increases mechanical rotational resistance in the threaded connection. Confirm locking parameters, temperature range and reinstallation conditions for the specific product. The screw standard alone does not specify these properties.

How do you select a socket head screw with pre-applied treatment?

• Thread: establish diameter and pitch matching the nut or component hole.
• Length: account for fixed-part thickness, hole depth and required thread engagement.
• Cylindrical head: check diameter, height and any recess in the part.
• Hexagon socket drive: compare socket size and the possibility of axial tool access.
• Pre-applied treatment: check its position relative to the thread section engaged in the connection.
• Material and class: match them to required loads and the operating environment.

What should be considered during installation?

Nylon locking treatment causes additional insertion resistance. The installation procedure should account for this effect. Do not equate resistance to screw rotation alone with correct clamping. Use the parameters specified for the selected connection and locking treatment.

Questions about DIN 912 with nylon

Does every socket head screw have pre-applied treatment?

No. The locking type must follow from the description or documentation of the specific item.

Is the screw suitable for repeated installation?

Check permission and cycle count for the treatment used. These cannot be determined solely from the DIN 912 name.

How do you prepare an enquiry for NERON in Piła?

State the standard, thread diameter and pitch, length, material, class, required KLF variant and number of pieces. Other head shapes are in the category screws with pre-applied thread treatment.
