304 Stainless Steel Quick Release Pins: Define the Fit and Grip Length

This product page covers 304 stainless steel quick release pins with a silver appearance. To select or manufacture a suitable pin, the shaft dimensions, effective grip length, locking arrangement and mating assembly must be defined together. HKAA reviews custom requirements against the customer drawing and agreed acceptance criteria.

Dimensions Needed for Selection

• Pin diameter: state the nominal diameter and required fit with the mating hole.
• Effective grip length: define the distance that must span the retained assembly, using the reference points on the pin drawing.
• Overall dimensions: include the head, button and any clearance required for operation.
• Locking position: show where the locking elements must sit relative to the retained parts.

Overall pin length and effective grip length are different dimensions. Include the assembly thickness and any washers, brackets or other retained items so the required length can be reviewed without relying on a product photograph.

Mating Hole and Assembly Access

Specify the mating hole size, tolerance, edge condition and the thickness of the retained components. Explain whether the pin must provide location, retention or both. The surrounding assembly should provide access to operate the release button and insert or remove the pin as intended.

For assemblies using a separate plate, our custom mounting plate information explains the hole-pattern and datum details to include with a machining RFQ. Compatibility between the plate and pin must be confirmed for the specific design.

Material and Silver Surface Appearance

State the required material for the pin shaft and identify any separate requirements for the head, button, spring or locking elements. A 304 designation for one part should not be assumed to describe every component of an assembly.

Define the surface finish with a drawing requirement or an agreed reference sample. Silver describes an appearance; it does not by itself establish roughness, polishing method, cleaning requirements or suitability for a particular environment.

Inspection and Functional Requirements

Include the critical dimensions to inspect and any required operating checks. Where retention force, working load, repeated operation or environmental performance matters, provide the required test method and acceptance criteria for review. Dimensions and material grade alone do not establish a load rating.

Related manufacturing capabilities include CNC turning for cylindrical features. The complete supply scope, including purchased parts and assembly, should be specified separately in the quotation request.

Quick Release Pin RFQ Checklist

• Dimensioned pin drawing and mating assembly information.
• Diameter, effective grip length, head style and locking arrangement.
• Material and finish requirements for the relevant components.
• Quantity, inspection records and any functional test criteria.
• Packaging, marking and requested delivery requirements.

Use the inquiry form on this page to describe your pin and assembly. Final specifications and supply scope are confirmed during the quotation review.

Frequently Asked Questions

Is overall length the same as grip length?

No. Use the dimension references on the pin drawing to define the retained thickness and the effective grip length required by the assembly.

Does a silver finish identify the exact surface treatment?

No. Specify the required surface condition, appearance reference and cleaning or finishing process where these are important.

Can a pin be selected only by shaft diameter?

Diameter is only one requirement. Grip length, hole fit, locking position, head clearance and the intended loading must also be reviewed.
