Blue Red Nylock Hexagon Torx Cross Recess Pan Head Machine Screw Din7985 Stainless Steel Ss201 304 316 316l A2 A4

This pan head machine screw offers three drive options – hexagon head, Torx, and cross recess – with a pre-assembled nylon locking ring (Nylock) available in blue or red. The nylon ring creates prevailing torque when engaged, effectively resisting vibration loosening. Materials include stainless steel SS201, SS304, SS316, SS316L, corresponding to German grades A2/A4. The pan head (DIN7985) provides a large bearing surface, ideal for thin sheets or soft materials. The blue or red nylon ring not only provides anti-loosening function but also serves as colour coding – blue often indicates A2, red indicates A4, for easy on-site identification. The combination of cross recess, Torx, and hexagon drives accommodates different assembly tool preferences.

• Food processing equipment – red ring indicates A4 stainless, resists detergents.

• Outdoor telecom cabinets – blue ring indicates A2, vibration-proof with easy ID.

• Medical device housings (non-implantable) – 316L plus nylon lock for long-term reliability.

• Rail vehicle interiors – Torx drive with nylon ring resists vibration.

• Automation equipment access panels – three drives suit different workstations

• Nylon ring anti-loosening – reliable vibration resistance, reusable.

• Colour coding – blue/red rings differentiate material or torque grade.

• Three drives in one – accepts hex key, Torx bit, or Phillips driver.

• Multiple materials – from economical 201 to highly corrosion-resistant 316L.

• DIN7985 pan head – large bearing area protects thin workpieces.
