Hi-Tech Fasteners, Inc. - REELFAST® KEYHOLE® Standoffs – Type SMTSK™ - Unified

PEM® surface mounted standoffs that eliminate the need for attaching screws

PEM® SMTSK™ standoffs are designed so that a PC board or panel can be quickly slipped into place and then removed from an assembly by simply sliding the board sideways and lifting it off. These standoffs mount on PC Boards in the same manner and at the same time as other surface mount components prior to the automated reflow solder process.

Reduces scrap, handling and risk of board damage.

Unique barrel design allows for quick attachment and detachment.

Makes horizontal or vertical component mounting possible.

Provided on tape and reel compatible with existing SMT automated installation equipment.

¹ The “L” dimension is the height of the installed stud at max grip. The height of the stud will increase if it is installed into thinner material. To calculate “actual L” use this formula: max grip - actual grip + L = “actual L” ² Packaged on 13" recyclable reels. Tape width is 24mm and 16mm. Pitch is 16mm and 12mm. Reels conform to EIA-481. ³ (1) See PEM® Technical Support section of our website for related plating standards and specifications. (2) Optimal solderability life noted on package. (3) The tin deposit on SMTSK standoffs meet the requirements of ASTM B545, Class A and althoug ⁴ To minimize sheet distortion and maximize product performance, use a centerline-to-edge value greater or equal to the value specified.
