Simpson Column Caps

Simpson Strong-Tie column caps are designed to lock beams securely to columns while spreading heavy loads evenly. By increasing the bearing area at the top of a column, they create a stronger, more stable connection that keeps large structures, like decks, patios, pergolas, and timber frames, standing firm. Whether you’re tying wood to wood, wood to steel, or handling multiple intersecting beams, there’s a cap engineered for the job.

Bolted Column Caps

CC Column Caps: Provide a larger bearing surface at the top of the column, increasing load transfer and stability. Certified welds ensure durability, and the design helps align beams with precision.

CCC Cross Column Caps: Perfect for jobs where multiple beams intersect at 90°. They distribute forces evenly across all beams while maintaining the structural integrity of the column below.

CCT T-Style Column Caps: Designed for “T” shaped layouts, these caps give support where a single beam intersects a column perpendicularly, distributing the load efficiently across both members.

ECC End Column Caps: Built for end-beam conditions, these caps strengthen the connection while expanding the bearing area to reduce stress on the wood.

ECCL L-Shaped End Column Caps: Designed for “L” beam layouts, ECCL caps keep corner structures locked down and stable under shifting loads.

SDS Screw Column Caps

CCQ Column Caps: Use Strong-Drive SDS Heavy-Duty Connector screws for a faster, cleaner install while still providing an extended bearing surface for dependable load transfer.

CCQM Column Caps: Flush-mounted solution for beams in non-corner locations, often used in floor framing where alignment and speed are critical.

CCTQM Column Caps: Similar to CCQM but with a side stirrup for securing intermediate beams in floor systems.

CCCQM Column Caps: Handles beams intersecting at 90° in floor framing, giving a secure, tight connection without complicated hardware.

ECCLQ Column Caps: An “L”-shaped version for layouts where beams turn corners, keeping connections solid and aligned.

CCCQ Column Caps: Designed to tie multiple beams together on top of a column while distributing loads across the full bearing area.

CCTQ Column Caps: “T” formation column caps that provide support for mid-span beam layouts.

ECCQ End Column Caps: End-beam solution with SDS screws for a quicker install while maintaining load distribution at termination points.

Lally & Steel Column Caps

CCOS Column Caps: A heavy-duty option for steel applications, designed for field welding to steel columns. The CCOS handles high-capacity loads and adapts to a variety of layouts.

LCC Column Caps: Weld directly to lally columns with side plates that secure beams in place, offering a safe and reliable connection. These are the go-to choices for jobs that call for steel-to-wood integration.

GFCMU & Concrete Pier Applications

Simpson also engineers column caps that connect beams to concrete or masonry piers. These specialized designs maintain structural integrity while adapting to unique foundation types, ensuring that beams are securely tied into non-wood supports.

Why They Matter

A column can only do its job if the load above it is transferred cleanly into the foundation. Without a strong column cap, weight isn’t distributed properly, leading to stress cracks, sagging, or even failure over time. Simpson column caps solve this by reinforcing the top connection, stabilizing the beam layout, and often eliminating the need for extra bracing. From bolted connections to screw-fastened systems and steel-to-lally solutions, these caps are built to handle serious structural demands while saving time on installation.
