Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of PresentationTriMas Corporation ("TriMas" or the "Company"), and its consolidated subsidiaries, designs, engineers and manufactures innovative products under leading brand names for customers primarily in the consumer products, aerospace & defense, and industrial markets.The preparation of financial statements requires management of the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities. Actual results may differ from such estimates and assumptions due to risks and uncertainties, including uncertainty in the current economic environment due to the ongoing outbreak of the coronavirus and related variants (“COVID-19”). While the full impact of the COVID-19 pandemic is unknown and cannot be reasonably estimated at this time, the Company has made appropriate accounting estimates based on the facts and circumstances available as of the reporting date. To the extent there are differences between these estimates and actual results, the Company's consolidated financial statements may be materially affected.
