What Fastenal puts in, and what the plan costs
What Fastenal put into the plan, per active participant
$1,106
Fastenal Company put $1,106 into this plan for each of its 17,820 active participants in plan year 2024. This is the whole employer side of the plan: matching money, profit sharing, non-elective and safe-harbor contributions, and reallocated forfeitures. The Form 5500 does not separate them, so this is what the employer put in and not the match.
Fastenal put in more per active participant than 74% of plans with 5,000+ participants in retail. The middle plan in that group of 196 reported $700. Retail comes from business code 444130, which Fastenal entered on its own Form 5500. Sponsors pick that code themselves, so a code that does not describe what the employer does ranks the plan against the wrong companies.
Matched to this employer by sponsor name, not by an identifier stated in the filing. This record could cover another plan of the same employer.
What this figure cannot separate: how much Fastenal pays, and how much it puts in
This is dollars, not a rate. A Form 5500 carries no payroll, so the figure reflects both how much the employer puts in and how much the employer pays: two plans running the same formula report different amounts when one pays better. Crossing the peer group with industry holds most of that difference still, and none of it disappears.
This is one plan year, not an average. A true-up, a plan merger or a one-off contribution moves a single year on its own.

What Fastenal puts in
Not stated in the filing
The match rate is set at the company's discretion each year, and the filing does not state the rate it used.
The Form 5500 for this plan reports what Fastenal actually paid in: the figure and its peer comparison are above. It is the whole employer side of the plan on one line, so it answers what went in rather than what the formula promises.
Two places state the terms in full: your plan’s Summary Plan Description, which your employer must provide on request, and your recordkeeper’s site, which for this plan is Merrill Benefits OnLine ↗.
What you contribute to collect all of it
Not stated in the filing
The filing does not state the contribution rate that collects the full employer contribution.
Vesting score
100 out of 100
How fast the employer’s money becomes yours. Higher than 48% of the 253 schedules we have scored.
It measures vesting speed and nothing else. It says nothing about the size of the match, what the plan charges, or the funds inside it.
Share of the employer's money that is the worker's at hire and at each of the first 6 anniversaries: 100%, 100%, 100%, 100%, 100%, 100%, 100%. The score is the average of those 7 readings.
Vesting, word for word
“The Plan's discretionary employer matching contributions are 100% vested when made. Discretionary contributions are reported as an employer contribution receivable on the Statement of Net Assets Available for Benefits and were paid to the Plan subsequent to the respective year end.”
The wait before the match starts and the year-end true-up appear above when the filing states them. Neither is part of the score, and a filing that is silent on one of them is not a plan without it.
What the plan costs, against plans of its size
20th percentile
$26.59 per participant in plan-paid administrative cost, cheaper than 80% of plans with 5,000+ participants.
What is Fastenal's 401(k) match formula?
Fastenal sets its 401(k) match at its own discretion each year and does not state the rate in this filing. The match is deposited once a year. A discretionary match is set again each year, so the rate in force lives in the plan document rather than the filing. The four shapes a formula takes is what to look for when you read one.
| Deposited | Once a year |
|---|---|
| Conditions | Employer matching contributions are discretionary; no rate or formula is disclosed. Discretionary contributions are reported as a receivable and paid to the Plan subsequent to the respective year end ($22,245,913 for 2025). |
What the filing says, word for word
“Contributions to the Plan include (i) salary deferral contributions authorized by participants, (ii) participant rollover contributions from another qualified plan, and (iii) discretionary matching contributions made by Fastenal.”

What is Fastenal's 401(k) vesting schedule?
Fastenal vests the employer match immediately: 100% is yours as soon as it is paid in. Nothing is forfeited when you leave, which is not true of the two schedules that vest over time.
| Employer match vesting | Immediate: employer match is 100% vested when contributed |
|---|---|
| Your own contributions | Immediate: always 100% yours |
