Philips Pan Head Machine Screws-Alloy Steel Cross Screw

description

1.Superior Mechanical Performance

Manufactured from high-grade alloy steel and precision quenched & tempered, these Phillips pan head machine screws deliver exceptional strength and durability. Typical tensile strengths exceed 800 MPa (116 000 PSI) with yield strengths above 600 MPa (87 000 PSI), and hardness values of 28–32 HRC. The generous pan head profile resists deformation under high torque, while a uniform zinc-plated or black-oxide finish offers moderate corrosion protection and maintains tight dimensional tolerances.

2.Versatile Application Range
Engineered for fastening into pre-tapped holes or with nuts, these screws excel across electronics enclosures, control panels, appliance assemblies, automotive interior trim, metal furniture, instrumentation housings, and light industrial machinery. Their broad compatibility with steel, aluminum, and engineered plastics makes them ideal for both prototype builds and high-volume production lines.

3.Effortless Installation
The cruciform Phillips drive provides reliable bit engagement and self-centering action, minimizing cam-out and reducing driver wear. Standard thread tolerances ensure smooth insertion and precise alignment in pre-tapped holes, while compatibility with manual and power drivers accelerates assembly speed. The pan head’s large bearing surface spreads clamping force evenly, eliminating the need for separate washers.

4.Premium Quality and Reliability
Produced in ISO 9001-certified facilities, each batch undergoes rigorous quality control, including dimensional inspection (±0.1 mm), drive-engagement testing, hardness verification, and plating-thickness measurement (≥8 μm for zinc). Salt-spray performance meets or exceeds 48 hours per ASTM B117. Full material traceability and batch certificates are available for critical applications requiring documented supply-chain integrity.
