Product Brief

ISO7380 button head torx pin machine screw features a neat and aesthetic round‑head profile. The torx drive delivers stable torque output. Equipped with an anti‑tamper pin in the head, it prevents unauthorized disassembly and cannot be removed by standard bits. Its machine‑thread ensures firm connection, widely used for assembly of equipment housings, home appliances, security instruments and chassis cabinets.

Product Features

Adopting tamper‑resistant torx‑pin drive, it can only be assembled and disassembled with special hollow torx pin bits to effectively avoid unauthorized disassembly. Available materials: 304/316 stainless steel, carbon steel and alloy steel, suitable for various indoor and outdoor working conditions. Surface finishes optional: zinc plating, black oxide, e‑coating, Dacromet and natural stainless steel finish. Complete size range, non‑standard customization per drawing is available; head type, thread and length can be adjusted as required. Manufactured in compliance with ISO7380 standard with high‑precision head dimensions for excellent fitting performance during assembly.

Technical FAQ

Q1: Can standard torx bits drive ISO7380 button head torx pin screws? A: No. Built‑in anti‑tamper pin blocks standard solid torx bits from applying force. Special hollow tamper‑proof torx pin bits are required for installation and removal to realize anti‑theft and anti‑disassembly performance.

Q2: Are ISO7380 and GB/T70.4 standards identical? A: They share basically equivalent dimensional benchmarks. ISO7380 is the international standard while GB/T70.4 is its corresponding Chinese national standard. Head and thread dimensions are interchangeable. Confirm material and surface finish during procurement.

Q3: What material and surface finish are recommended for outdoor applications? A: 304/316 stainless steel with natural finish is preferred for long‑term outdoor service. For carbon‑steel screws, Dacromet treatment is recommended. It provides better anti‑rust performance than ordinary zinc plating and e‑coating to lower rusting risks.

Q4: Are non‑standard length and modified special head types available? A: Yes. Customization is available according to customer drawings. Thread specification, screw length and head thickness are all adjustable. OEM sampling and mass production services are provided.

Q5: What torque precautions apply to torx pin machine screws? A: The torx drive offers stable torque output. Avoid over‑tightening during assembly. Control torque for stainless‑steel screws to prevent thread galling and thread stripping.

Q6: What is the minimum available size? A: Regular stock covers M2‑M10. Smaller or extra‑large sizes can be custom‑produced. Please consult our sales for lead‑time confirmation.
