UNSPSC 31163305: Anti-loosening device

Fastening device that prevents loosening of bolts and nuts due to vibration and external force

UNSPSC 31163305 Anti-loosening device is a Commodity code with limited recent state and local procurement activity directly aligned to fastening hardware. The recent opportunities tagged to this code show little relevance to anti-loosening devices specifically. One opportunity—a Dallas Water/Material Services Division RFQ for fastening, packaging, strapping, and tying equipment and supplies due June 25, 2026—touches fastening broadly but does not isolate anti-loosening hardware as a distinct line item or focus area. The remaining records in the recent-opportunities block are either administrative notices (a Williamson County purchasing department relocation announcement), vendor networking and trade show events unrelated to specific procurements, or educational forums about government contracting processes. No state or local jurisdictions issued RFPs, RFQs, ITBs, or IFBs specifically for anti-loosening devices, lock washers, thread-locking compounds, or mechanical fastener security components during the timeframe reflected in the source.

The code shows no meaningful recent activity among state departments, counties, cities, school districts, transit authorities, or special-purpose districts pursuing anti-loosening hardware as a standalone procurement category. Geographic spread cannot be characterized because no representative opportunities exist to support a regional distribution pattern. Anti-loosening devices may be embedded within larger fastening or MRO supply contracts (such as blanket purchase orders for general industrial supplies or fleet maintenance), but state and local procurement offices do not appear to solicit them as a distinct commodity line with sufficient frequency or visibility to support targeted business development under this code at this time.
