DIN 7985

DIN 7985 metal screws with pre-applied nylon treatment have a cylindrical head with a rounded top and cross drive. The NERON Piła category leads to the 267-28 KLF variant. Match the thread, length, drive design and locking treatment parameters to the connection documentation.

DIN 7985 with nylon thread locking treatment

DIN 7985 machine screws engage a suitable nut or prepared internal thread. Here, “metal screw” does not automatically mean a self-drilling or self-tapping design. Check thread parameters and connection preparation before installation.

Selecting a cross drive

Determine bit type and size from the specific design. PH and PZ drives should not be treated as interchangeable merely because both are cross-shaped. The correct bit and axial tool guidance help transmit tightening torque properly and reduce the risk of recess damage.

Pre-applied nylon treatment 267-28 KLF

Check the subcategory for pre-applied nylon treatment 267-28 KLF. Nylon applied to the thread increases mechanical rotational resistance. Locking type, position and conditions of use are separate parameters from the DIN 7985 designation. Reinstallation requires confirmation in the product documentation.

What should selection consider?

Thread: diameter and pitch matching the hole or nut.
Length: fixed-part thickness, hole depth and required thread engagement section.
Head: diameter, height and bearing surface.
Drive: cross drive type and bit size specified in the specification.
Material and class: mechanical properties and surface protection.
Nylon layer: matching position and parameters to the operating location.

Questions about DIN 7985 with pre-applied treatment

Does pre-applied treatment replace screw tightening?

No. Additional insertion resistance must be included in the installation procedure, but it does not confirm achievement of the required clamping force.

Does the DIN number alone specify nylon type?

No. The basic product designation does not give all thread-locking parameters.

What should an enquiry to NERON in Piła include?

Prepare DIN 7985, thread diameter and pitch, length, drive type, material, class, KLF requirements and number of pieces. Other geometries are in the category screws with pre-applied thread treatment.
