Import Breakaway Bolt / Shear Bolt — Buy in wholesale FOB from Supplier in Taiwan

Breakaway bolts from Top Screw Metal Corp. are engineered for applications where permanent installation and tamper resistance outweigh removal requirements. These shear bolts feature a hardened steel or stainless steel 304 construction, with a tamper-resistant head that fractures at a preset torque during installation. Standard wrenches suffice for fitting; once seated, the bolt head shears away, leaving no purchase for extraction tools. The supplier notes that additional sizes and materials are available upon request, indicating a degree of configurability for volume buyers.

The dual material offering addresses distinct environmental exposures. Hardened steel suits dry, protected installations where mechanical strength is paramount, while stainless steel 304 provides inherent corrosion resistance for outdoor or chemically exposed settings without reliance on surface coatings. The tamper-resistant head configuration is a deliberate security feature, not merely an incidental design trait. Preset torque fracture is controlled through material hardening and neck geometry, a standard approach in security fastening. Typical breakaway torque values for this class of bolt range from 15 Nm to 50 Nm depending on diameter and grade, though the supplier does not publish specific figures.

Utility meter housings, traffic signal fixtures, and infrastructure enclosures represent the primary import markets for this SKU. Regulated utility markets in particular demand hardware that meets published tamper-evidence standards. Buyers should confirm with Top Screw Metal Corp. whether the hardened steel variant carries any supplemental corrosion treatment, as bare hardened steel may require specification for coated or plated finishes in coastal applications. The response rate of 0.00% and zero recorded average response hours suggest that direct inquiry may require persistence; prospective importers should plan for delayed communication or engage through established procurement channels in Chang Hwa City.

Top Screw Metal Corp. is located at 78, Lane 415, Tay Ho Road, Section 2, Ku Yi Li, Chang Hwa City, Chang Hwa 500, Taiwan. The supplier is classified at harbor trust tier with a recorded response rate of 0.00% and zero average response hours, which indicates minimal or no recent engagement through the platform's messaging system. This pattern does not negate the supplier's operational status but signals that direct communication channels, including phone or trade show contact, may prove more reliable for procurement discussions than platform-dependent enquiry alone.

The listing focuses on security fasteners for regulated utility and infrastructure markets, with breakaway and tamper-resistant bolts as its featured product line. No employee count, annual revenue, factory certification, or client reference is stated in the supplier profile. The company does not claim ISO registration, nor does it publish production capacity or export territory data. Buyers evaluating Top Screw Metal Corp. should treat the absence of these data points as an information gap to close during supplier qualification, not as a disqualification, but should request documentation of quality management practices and prior export references before committing to volume orders.
