Graco 116475 – M4 × 12 Socket Head Cap Screw
Overview
The Graco 116475 is a metric socket‑head cap screw (thread size: M4, length: 12 mm). It’s used in Graco fluid‑handling and spray‑system assemblies to secure components — typically in confined or precision‑machined areas where standard bolts may not fit. ([official Graco parts list])
Key Features & Specifications
- Thread: M4, Length: 12 mm — standard metric sizing for small‑scale assemblies. ([parts catalog])
- Socket‑head cap screw (SHCS) design — cylindrical head with internal hex drive (Allen/hex key) for compact, flush mounting. ([fastener standards])
- Compact head — allows installation in confined spaces or counter‑bored holes where protruding bolt heads would interfere. ([fastener design reference])
- OEM‑grade Graco part — ensures correct dimensions, threading and reliable fastening in original assemblies. ([Graco parts documentation])
Compatible Assemblies / Machines
No publicly published exhaustive list of all Graco models using 116475.
116475 is documented in at least one Graco manifold assembly parts list — so it’s used in pump / fluid‑path modules. ([Graco manual excerpt])
If your unit corresponds to that assembly (or a similar compact module), check its parts breakdown. If 116475 (or “SCREW, SHCS, M4 x 12”) appears there, then this screw is the correct OEM replacement.
Why Use This Socket-Head Cap Screw?
This screw is useful when you need to:
- Provide secure, reliable fastening in compact or precision‑machined assemblies
- Use a clean, flush head to avoid interference — useful in confined housings or fluid‑handling modules
- Use genuine OEM‑grade hardware to maintain original build integrity and proper replacement fit
- Perform maintenance or replacement when original screw is lost, damaged, or corroded
Frequently Asked Questions
A socket‑head cap screw is a machine screw with a cylindrical head and a hexagonal recess. Instead of using a traditional wrench or spanner, you use an Allen/wrench bit — allowing installation in tight or confined spaces where a regular bolt head would not fit. These screws are widely used in machinery, tools, and equipment assemblies. :contentReference[oaicite:4]{index=4}
Yes — 116475 is listed in official Graco spare‑parts catalogs under the description “SCREW, SHCS, M4 x 12.” :contentReference[oaicite:5]{index=5}
Replace the screw if it's stripped, corroded, damaged, or missing — or when re‑assembling components that were disassembled for maintenance. Because M4×12 SHCS are typically used for precise internal assemblies, always use the exact OEM part (116475) or an equivalent of correct size and strength to maintain proper alignment and sealing.
