SAIMA has started stocking Low Head Tamper Screws.
As a specialty supplier of security screws, this is the first time SAIMA offers a low-profile type tamper-resistant screw as a standard stock item.
Growing Demand for Low-Head Screws
With the increasing trend toward thinner, smaller, and lighter devices, low head screws such as 310Slim Machine Screws are being used more frequently.
In response to strong market demand for low-profile security screws, we have started stocking:
- M3
- M4
- M5
These sizes are now available for immediate shipment.

Applications
1. Devices Regulated Under the Radio Law (Japan)
Under Japan’s Radio Law, equipment must not be designed in a way that allows easy opening by users.
Therefore, the use of tamper-resistant screws, such as the TRF series, is required.
As regulated devices continue to become thinner and lighter, Low Head Tamper Screws are an ideal solution for these applications.

2. Toys
For toys intended for young children, special screws are used to prevent disassembly and accidental ingestion of small internal parts.
Tamper-resistant screws play a critical role in ensuring product safety in this field.
Due to strong demand across these and other applications, SAIMA has added Low Head Tamper Screws to regular stock items.
Please refer to the stock list for detailed availability.
If you need the text refined further (more technical, more marketing-oriented, or adjusted for overseas distributors), I can tailor it to your target audience.
