Precision Manufacturing, Batch After Batch
From cold-heading raw steel wire to heat-treated finished bolts, every step runs under strict in-house process control — ensuring the dimensional accuracy and strength grade printed on every head marking.
Product Overview
Application Scenarios
Cross-recess countersunk (flat head) machine screws (DIN 965 / ISO 7046) have a 90° flat head driven by a Phillips cross recess, seating flush into a countersunk hole on a fully threaded machine-screw shank. They give a clean, snag-free flush finish and are widely used in electronics and electrical enclosures, appliances, sheet-metal and panel work, hinges, trim and general light assembly. Stainless versions suit visible, damp, outdoor and food-contact applications.
Installation Notes
Prepare a matching 90° countersunk hole so the flat head seats fully flush. Drive with the correctly sized Phillips bit — the recess number rises with screw size (PH1 for M3, PH2 for M4–M5, PH3 for M6, PH4 for M8–M10), and the wrong bit cams out and chews up the recess. These are machine screws: run them into a tapped hole, nut or captive thread rather than plain material. They are normally grade 4.8 or 8.8; a thread-locker resists loosening on vibration-prone joints, and a flush countersunk head seats on the workpiece without a washer.
Material & Certification
Manufactured from cold-heading quality carbon steel to grade 4.8 or 8.8 per ISO 898-1 and produced to DIN 965 / ISO 7046, with every batch traceable to raw material certificates. Each production run passes 100% dimensional and cross-recess gauge inspection before packaging; EN 10204 3.1 material certificates are available on request.
