Description

Contessa SP08 Replacement Screws for Picatinny Rails

The Contessa SP08 Replacement Screws are precision-made fasteners designed as direct replacements for Contessa Picatinny rail systems. Manufactured from high-quality steel, these screws provide secure fastening, long-term durability, and reliable performance under recoil.

They are intended for shooters and gunsmiths who need to replace lost, damaged, or worn Picatinny rail screws while preserving the integrity of their Contessa mounting system.


Designed for Contessa Picatinny Rail Systems

These screws are engineered specifically for Contessa Picatinny rails and should not be considered universal hardware. Using the correct screw specification is essential to ensure proper thread engagement, torque, and rail stability.

To help identify the correct replacement, Contessa provides multiple SP08 screw variants based on thread type and length.


Available SP08 Screw Variants (Size Identification)

The Contessa SP08 screw set is available in the following screw size configurations:

  • SP08/A – 6/48 UNS

  • SP08/B – 8/4 UN

  • SP08/C – 6/48 UNS (Long)

  • SP08/D – 3.5 MA

  • SP08/E – 3.50 MA (Long)

Refer to the product images to visually confirm the correct screw type and length for your specific Picatinny rail application before ordering.


Construction and Performance

SP08 screws are manufactured from steel and produced to Contessa’s precise tolerances to ensure:

  • Secure rail-to-firearm attachment

  • Resistance to loosening under recoil

  • Long-term durability with repeated installation and removal

  • Proper alignment of Picatinny-mounted optics and accessories

Using genuine Contessa screws helps prevent thread damage and mounting instability that can occur with non-matching hardware.


Why Use Genuine Contessa Replacement Screws?

Contessa replacement screws are designed to:

  • Match original factory specifications

  • Maintain the mechanical integrity of the rail system

  • Reduce the risk of improper fit or stripped threads

  • Preserve optic stability and zero retention

Generic screws may appear similar but often differ in thread pitch, length, or hardness.
