HES 003-0203-001 – Frequently Asked Questions

1) What does the HES 003-0203-001 spring actually do inside a 310 Series electric strike?
It is the latchbolt keeper spring. In a 310 Series strike, the keeper has to hold tension against the lock's latchbolt so the latch stays retained until the strike is released. When that spring weakens or breaks, the keeper loses tension and the strike stops retaining the latch consistently. The 003-0203-001 restores that tension, which is why it is the go-to part when a 310 strike starts releasing or holding erratically rather than failing electrically.
2) My 310 Series strike buzzes but the latch won't release cleanly. Is the keeper spring the part to replace?
That is exactly the failure this part addresses on the mechanical side. If the solenoid is energizing and the strike still won't retain or release the latch consistently, the keeper spring's tension is a prime suspect, and the 003-0203-001 is the component that restores it. It is a small-profile spring meant to be swapped into an existing 310 Series assembly during routine maintenance or repair, so you are servicing the strike in place rather than replacing the whole unit.
3) Is this a genuine HES part or an aftermarket spring?
Genuine OEM. The 003-0203-001 is HES's own replacement latchbolt keeper spring, supplied out of the Folger Adam Parts and Accessories line, and it is built to the same performance standards as the spring originally in the strike. For anyone maintaining access-controlled openings where the strike has to behave predictably, that matters more than it sounds: an off-spec spring changes the tension the keeper works at.
4) Do I get a whole keeper assembly with this, or just the spring?
Just the spring. The 003-0203-001 is a single replacement latchbolt keeper spring, not the keeper, faceplate, or solenoid. If the keeper itself is worn, bent, or the strike body is damaged, you will need the corresponding 310 Series component for that instead. Order this one when the spring is what failed.
5) How do I make sure I'm ordering the right HES spring the first time?
Order by the model number, 003-0203-001, and match it to a 310 Series strike. There is a single configuration of this spring, so there is no finish, handing, or size to specify, which keeps the ordering simple for anyone doing a parts pull against a maintenance ticket. What you do need to confirm is the strike series, since the part is series-specific.
6) Is the 003-0203-001 keeper spring rated for commercial door use, or is it a residential-grade part?
Commercial. HES classes the 003-0203-001 as a commercial door hardware component, and it is the part facilities crews use on 310 Series strikes in offices, schools, hospitals, retail, warehouses, government buildings, and multi-tenant residential with commercial-grade access control. If you standardize on 310 strikes across a portfolio, this is a sensible spring to keep on the shelf in quantity.
