About NIGP 55351
NIGP 55351 Machine-Made Parts (Metal, Non-Metal, Screw, Etc.), an Item code, covers metal and non-metal fabricated components and fasteners that state and local governments procure for equipment maintenance, infrastructure repair, and operational support. Recent solicitations show state and local buyers purchasing stainless steel diaphragm plates, screw fasteners, sign posts with mounting hardware, door lock cylinders, ADA-compliant ramps and platforms, thermoplastic applicator equipment components, and HVAC parts and supplies. The issuing bodies under this code span higher-education systems, county governments, and county-level special districts; Harris County, Texas appears as a repeat buyer across multiple recent ITBs covering fasteners, hardware, platform components, and related fabricated items. Work is solicited primarily through invitation-to-bid (ITB) notices with firm deadlines and all-inclusive pricing requirements, often including warranty, installation, training, and responsive maintenance-support provisions alongside material supply.
Recent activity concentrates in Texas, with the Texas A&M University System posting an ITB for stainless steel diaphragm plates due October 28, 2026, and Harris County issuing multiple ITBs since May 2026 covering screw fasteners and related items (due August 24, 2026), sign posts and mounting hardware (due September 21, 2026), election ADA ramps, platforms, rails, and accessories (due June 15, 2026), door lock replacement components at juvenile detention facilities (due June 15, 2026), and thermoplastic applicator machine and trailer equipment (due June 8, 2026). A Monroe County, Florida procurement for seven replacement hollow metal doors and frames at the Sheriff's Office Hangar in Marathon (due July 29, 2026 via Bonfire) signals activity in South Florida. Contracts typically run one year with optional renewal terms subject to board or commissioners court approval, require M/WBE good-faith efforts in Harris County procurements, mandate comprehensive insurance naming the county as additional insured, and enforce local minimum-wage requirements where contract value exceeds applicable thresholds.
