0351 Holey Star Screwdriver | Ergonomic PP Handle | SNCMVH Steel

Technical Architecture & Mechanical Logic

• Holey Star (Tamper-Proof) Geometry: This screwdriver features a 6-lobe Star tip with a precision-machined center hole. This mechanical logic allows the tool to seat fully over the security pin of “Resistorx” or Tamper-Proof Star fasteners, which a standard solid Star driver cannot engage.
• SNCMVH High-Grade Alloy Steel: The integrated shaft and tip are forged from Hans’ premium alloy of Silicon (S), Nickel (N), Chrome (C), Molybdenum (M), and Vanadium (H). This metallurgy provides the superior hardness-to-toughness ratio required to prevent tip deformation while applying high manual torque to stubborn security bolts.
• Ergonomic PP Handle: The handle is manufactured from high-impact Polypropylene (PP), architected for a comfortable palm fit. This design maximizes the transfer of rotational force from the user’s hand through the SNCMVH shaft to the Holey Star tip.
• Complete Professional Range (TH10–TH40): As per the technical table, the 0351 series is available in the following size and length progressions:
  • TH10 x 100mm, TH15 x 100mm, TH20 x 100mm, TH25 x 100mm, TH27 x 100mm, TH30 x 100mm, and TH40 x 150mm.
• High-Polish Chrome Finish: The steel shaft is treated with a professional-grade chrome finish for maximum resistance to oxidation and workshop solvents.

B2B Procurement & Workshop ROI

• Specialized Security Capability: The 0351 allows technicians to service tamper-resistant components immediately, eliminating downtime caused by a lack of specialized security tooling.
• Industrial Fatigue Resistance: The use of SNCMVH steel ensures the 0351 outlasts standard Chrome Vanadium (Cr-V) screwdrivers, delivering a lower Total Cost of Ownership (TCO) through reduced tip wear.
• Precision Tip Engagement: CNC-machined flutes ensure a zero-tolerance fit, protecting expensive security fasteners from internal stripping and reducing extraction rework.

FAQ Section

• What does “Holey Star” mean? It refers to a Star (Torx) screwdriver with a center hole, specifically used for Tamper-Proof screws that have a central security pin.
• Is the handle chemical-resistant? Yes, the PP (Polypropylene) handle is designed to withstand common workshop oils and chemicals.
• What is the benefit of SNCMVH steel? For integrated screwdrivers, Hans uses SNCMVH for maximum torsional endurance in a full-length shaft, whereas S2 Steel is reserved for Hans Screwdriver Bits.
• What sizes are available? According to the technical table, the 0351 series covers TH10 through TH40.
