Questions and answers
How many retirement plans are there in machine shops; turned product; & screw, nut, & bolt mfg?
187 plans with 100 or more participants filed Form 5500 for plan year 2024, out of 373 pension plans on the full form. Smaller plans file Form 5500-SF and are counted separately where shown.
What is the typical 401(k) balance in machine shops; turned product; & screw, nut, & bolt mfg?
The median defined contribution plan reported $61,755 in net assets per participant (middle half of plans: $40,143 to $82,254); nationally it was $53,031. This is a plan-level average that includes former employees, not a typical person's balance.
What do employers contribute in machine shops; turned product; & screw, nut, & bolt mfg?
The median defined contribution plan received $1,869 in employer contributions per active participant, against $2,174 nationally. Plans with no employer contribution are included at zero.
What are average 401(k) fees in machine shops; turned product; & screw, nut, & bolt mfg?
Among defined contribution plans that report any Schedule C compensation, the median was $192 per participant and 0.35% of net assets (nationally $123 and 0.26%). Schedule C leaves out fund expense ratios and fees the employer pays, so it understates total cost.
Where does this come from?
Form 5500 annual reports in the EBSA research files, with filings received through 24 Aug 2026. Medians are computed by this site across plans with 100 or more participants.
